Effective reasoning preparation for competitive exams has five working parts: understand the logic behind each topic, learn a repeatable solving method, align your topic priorities with the exam you are taking, practise under time limits, and study your mistakes until they stop recurring. Memorising shortcuts without the logic behind them can prevent candidates from improving.
This guide teaches that method from scratch. It covers what Reasoning Ability tests, how Banking, SSC and Railway papers differ, how to learn each topic family, how to solve arrangements and puzzles step by step, how to use mocks and an error log, and how to plan 30, 60 or 90 days.
Every worked example in this article is original and has been re-checked. For the broader recruitment picture, see PREPON's Bank & Government exam preparation guide.
How to read the labels in this guide. A verified official fact comes from a recruiting authority's notice. A secondary-source observation comes from a coaching or news site and is not official. An editorial teaching recommendation is PREPON's advice on method. An illustrative example is an original practice question written for this guide, not a past-paper item.
What Is Reasoning Ability in Competitive Exams?
Reasoning Ability tests whether you can draw correct conclusions from limited information, quickly and without being misled by wording. You are not tested on outside knowledge. You are given a small set of facts, and you must work out what must be true, what may be true and what cannot be true.
Seven thinking skills sit underneath almost every question.
Deductive reasoning moves from general rules to certain conclusions. If all clerks in a branch have ID cards, and Meena is a clerk in that branch, Meena has an ID card. The conclusion is guaranteed.
Inductive reasoning moves from observed cases to a likely rule. If a series reads 3, 6, 12, 24, you infer that each term doubles. Pattern questions rely on this, and the rule must still fit every term.
Constraint-based reasoning means satisfying several conditions at once. "Anil does not sit next to Beena" and "Beena sits at an end" together narrow the possibilities. Seating arrangements and scheduling puzzles are built on this skill.
Relational reasoning tracks how entities connect: older than, north of, father of, taller than. Blood relations, direction sense, ranking and inequalities all belong here.
Spatial reasoning means mentally rotating, folding, reflecting or counting shapes. Non-verbal questions depend on it.
Pattern recognition is spotting the rule behind letters, numbers or figures. Coding-decoding, series and input-output questions depend on it.
Logical evaluation is judging whether a statement, argument or action follows from given information. Analytical Reasoning questions test it.
The key habit across all seven is the same: separate what is stated from what you assume. A frequent source of wrong answers is treating an assumption as a fact. Build that habit early in your reasoning preparation for competitive exams.
How Reasoning Differs Across Banking, SSC and Railway Exams
All three exam families test reasoning, but they weight different skills, so reasoning preparation for competitive exams cannot be identical for each. Banking papers lean towards multi-step puzzles and arrangements. SSC papers test a broad spread of shorter questions that includes verbal and figure-based items. Railway papers carry a wide official syllabus list. Do not assume that preparing for one family automatically covers the others.

| Exam | Reasoning section | Questions | Marks | Time | Negative marking |
|---|---|---|---|---|---|
| SBI PO 2026 Prelims | Reasoning Ability | 30 | Aggregate Prelims: 100 marks (three sections) | 20 minutes, timed separately | One-fourth of marks assigned to the question; no sectional cut-off in Prelims |

| SSC CGL 2026 Tier-I | General Intelligence and Reasoning | 25 | 50 | 15 minutes (ordinary candidates) | 0.50 mark per wrong answer |
| SSC CGL 2026 Tier-II, Paper-I | Reasoning and General Intelligence | 30 | 90 | 30 minutes (ordinary candidates) | 1 mark per wrong answer in Section-I |
Sources: SBI PO 2026 advertisement CRPD/PO/2026-27/09 (Section 8, Selection Procedure) and the SSC CGL 2026 notice dated 21 May 2026 (Sections 13.8 and 13.9). These 2026 notice tables were independently checked against the published official PDFs. Always re-check the notice for your own cycle before building a timing plan.
Three cautions apply. SBI's Main section is titled "Reasoning & Computer Aptitude", but Computer Aptitude is a separate subject that shares the paper. It is not a branch of Reasoning Ability. SSC CGL Tier-II also has a separate Computer Knowledge Test. For IBPS PO/MT-XVI, the official recruitment page confirms the cycle, but published secondary-source figures for the Main Reasoning section disagree with one another (a secondary-source observation, not an official fact), so check IBPS's own handout rather than relying on a coaching site.
Railway examinations
The RRB NTPC CEN 05/2024 syllabus lists analogies, number and alphabetical series, coding and decoding, mathematical operations, similarities and differences, relationships, analytical reasoning, syllogism, jumbling, Venn diagrams, puzzles, data sufficiency, statement–conclusion, statement–courses of action, decision making, maps and interpretation of graphs.
That is the 2024 cycle. The RRB notice index lists later NTPC notices, including CEN 06/2025 and CEN 07/2025, so confirm which cycle applies to you. Topic mix and question counts can differ between cycles and between Railway posts.
Practical differences in what you must train
| Area | Banking Prelims | Banking Mains | SSC Tier-I and II | RRB CBT |
|---|---|---|---|---|
| Typical emphasis | Speed on standard puzzles and short sets | Longer, denser constraint sets | Many short, varied questions | Wide syllabus list; check the notice |
| Extra skill to train | Selecting solvable sets quickly | Multi-variable puzzles; conditional logic | Verbal, symbolic and figure-based items | Breadth across the listed topics |
| Main risk | Over-investing in one hard puzzle | Time lost on a set that will not resolve | Weakness in neglected topic types | Gaps from preparing only for Banking |
This table is editorial guidance on training emphasis, not an official topic-weight statement. No recruiting authority publishes a fixed topic-wise question allocation, so treat any claim of exact percentages with suspicion.
Common preparation base: syllogisms, inequalities, blood relations, direction sense, ranking, coding-decoding, series, data sufficiency and basic analytical reasoning. This is a sensible base for building skills. It is not a claim that every exam formally tests every one of these topics. Specialised extensions: advanced arrangements for Banking Mains; non-verbal reasoning and symbolic operations for SSC and Railway preparation.
Complete Reasoning Syllabus: What Topics Should You Study?
Treat the syllabus as eight instructional groups rather than a flat list of separate topics. Each group shares a core skill, so mastering one makes the next easier, and organising reasoning preparation for competitive exams around these groups keeps coverage complete. The groups below are practical editorial groupings. PREPON's academic classification of Analytical Reasoning is separate and appears in its own subsection.
| Group | Core skill | Topics inside |
|---|---|---|
| Logical statements | Reading quantifiers precisely | Syllogisms |
| Relational chains | Combining pairwise relations | Inequalities, blood relations, ranking |
| Spatial-relational | Tracking position and movement | Direction sense, ordering |
| Pattern rules | Detecting and applying a rule | Coding-decoding, series, analogies, classification, input-output |
| Sufficiency judgement | Judging if information is enough | Data sufficiency |
| Constraint structures | Satisfying many clues at once | Arrangements and puzzles |
| Analytical Reasoning (PREPON) | Evaluating statements and arguments | Eight approved topics |
| Non-verbal and spatial | Transforming figures mentally | Figure series, mirror and water images, folding, cubes and dice |
Syllogisms
In reasoning preparation for competitive exams, syllogisms reward precise interpretation rather than memorised diagrams alone.
A syllogism gives two or three statements about groups and asks which conclusions must follow. Learn four statement types: All A are B, Some A are B, No A is B and Some A are not B.
Study these sub-areas in order: basic all/some/no relationships; "possibility" conclusions; "only" and "only a few" wording; and coded syllogisms where symbols stand for relations.
Two cautions matter. Read the paper's instructions on whether "All A are B" is taken to imply "Some A are B", because conventions differ. Never import real-world facts: only the given statements count. The common mistake is concluding "Some A are C" from two "Some" statements, which does not follow.
Inequalities
Inequalities test whether you can chain symbols such as >, ≥, = and ≤ into a reliable conclusion. Learn direct inequalities, coded inequalities (where symbols stand for relations), combined chains, either-or conclusions and indeterminate cases. A relation holds only if one unbroken chain runs in a single direction. Chains that meet at a "peak" or a "valley" give no relation between the two ends. This works because ≥, > and = pass along a chain only when they point the same way. Two quantities that are both above (or both below) a shared term tell you nothing about each other.
Blood Relations
Blood relations are an essential diagramming exercise in reasoning preparation for competitive exams.
Draw a family tree rather than holding relations in your head. Cover direct relations, puzzle-style relations, coded relations and generation counting. Mark gender only when it is stated or forced. Unstated gender is the most frequent source of wrong answers.
Direction Sense
Convert every movement into coordinates. Cover relative directions, turns, shortest distance and final direction. Treat north as the positive y-axis and east as the positive x-axis, and use the distance formula with Pythagorean triples to save time. This works because coordinates turn a path into simple additions, so you never rotate a picture in your head. It becomes unsafe only if you misread a turn, so write the facing direction beside each leg.
Ordering and Ranking
Learn the rank-from-left and rank-from-right relationship, relative positions, interchange of positions and population counting. The master relation is: total = (rank from one end) + (rank from the other end) − 1. It works because the person is counted once in each rank, so adding the two ranks counts that person twice. It is unsafe when the two ranks refer to different rows or groups.
Coding-Decoding
Coding-decoding makes reasoning preparation for competitive exams more systematic when you test each transformation against every character.
Cover letter shifts, number transformations, substitution, conditional coding and symbol-based formats. The method is to compare the input and output position by position, state the rule in one sentence, and test it on every letter before applying it.
Series and Pattern Recognition
Cover alphabet series, number series, alphanumeric sequences, mixed-symbol series, analogies and classification. Number series reward a fixed checking order: differences, ratios, squares and cubes, then alternating or combined rules.
Input-Output
Input-output questions show a machine that rearranges a list in steps. Learn to name the rule of each step (sort, swap, shift, reverse), then predict the final step without running every intermediate one. Complex versions mix two operations at once.
Data Sufficiency
For reasoning preparation for competitive exams, Data Sufficiency needs a different mindset from ordinary problem solving.
Data sufficiency asks whether information is enough to answer, not what the answer is. Judge each statement alone, then both together, and check that the answer is unique. Stopping the moment you reach a number is a different skill from judging sufficiency, and mixing them up costs marks.
Arrangements and Puzzles
The most effective reasoning preparation for competitive exams treats arrangements as problems in satisfying multiple constraints, not as guesswork.
This group covers linear, circular, parallel-row and mixed-direction seating; floor, floor-and-flat and box puzzles; scheduling; distribution; grouping; and multi-variable logic. These belong to a structural, constraint-based group. PREPON does not classify them as Analytical Reasoning. The method is taught in full in a later section.
PREPON Analytical Reasoning
PREPON defines Analytical Reasoning as exactly eight topics: Statements & Conclusions, Statements & Assumptions, Statements & Arguments, Courses of Action, Assertions & Reasons, Causes & Effects, Truth Verification and Verbal Deductions. Each is taught with a worked example in its own section below. Truth Verification and Verbal Deductions are explained there through standard reasoning methods: checking claims for consistency, and drawing necessary conclusions from conditional statements.
An official Railway syllabus may use "analytical reasoning" more broadly than PREPON does. That difference is one of labelling, not of content. This article keeps PREPON's classification and notes the wider usage where it matters.
Related formats such as critical reasoning, drawing inferences, eligibility tests and decision making may appear in some papers. They are related question formats, not substitutes for the eight approved topics.
Non-Verbal and Spatial Reasoning
Cover figure series, figure classification, mirror images, water images, paper folding and cutting, embedded figures, pattern completion, cubes and dice, counting figures and spatial orientation. Whether and how heavily these appear depends on the exam and the year, so confirm against your notice rather than assuming a fixed share.
Topic relevance by exam family
| Topic family | Banking | SSC | Railway |
|---|---|---|---|
| Syllogisms, inequalities, blood relations, direction, ranking | Commonly practised | Commonly practised | Syllogism and relationship topics appear in the NTPC CEN 05/2024 syllabus list |
| Arrangements and puzzles | Central to most preparation plans | Verify against notice | Puzzles appear in the NTPC CEN 05/2024 syllabus list |
| Input-output | Commonly practised | Verify against notice | Verify against notice |
| Analytical Reasoning topics | Verify against notice | Verify against notice | Statement–conclusion, statement–courses of action and decision making appear in the CEN 05/2024 list |
| Non-verbal and spatial | Verify against notice | Prepare as a separate block | Verify against notice |
"Verify against notice" means PREPON does not assert a fixed pattern. Check the syllabus section of your cycle's official notice, and prepare broadly if it is unclear.
How to Build Reasoning Fundamentals from Scratch
Beginners often start with seating arrangements because they look important. That is usually the wrong first step. Puzzles combine several smaller skills, and a candidate who has not mastered those skills will fail for reasons that are hard to diagnose. Sound reasoning preparation for competitive exams follows dependency order instead.
| Level | What to learn | Why this order |
|---|---|---|
| 0 | Precise reading: all, some, none, only, if, unless, either, at least, exactly | Every later topic depends on exact reading of these words |
| 1 | Ranking, direction sense, blood relations, simple coding, number and alphabet series | Independent topics; each can be learned on its own |
| 2 | Inequalities, syllogisms, data sufficiency, input-output | Need Level 0 reading precision and basic chaining |
| 3 | Linear arrangements, then circular, then parallel rows, then floor, box and scheduling puzzles | Need ranking, relations and case-splitting |
| 4 | Multi-variable puzzles, conditional puzzles, Analytical Reasoning sets | Need all earlier representation habits |
| Parallel | Non-verbal practice in short daily blocks from the start | Spatial skill grows slowly and needs spacing |
Text explanation: Move through Levels 0 to 4 in sequence; use the yes/no checks to decide when to advance. Non-verbal practice runs in parallel.
Topics inside one level can be studied in any order. A candidate weak in Level 1 should not jump to Level 3, because puzzle practice will only repeat the same small errors on a bigger canvas. Start Level 0 on day one by rewriting ten sentences into precise logical form every day.
The examples below cover the foundation topics. Attempt each before reading the solution.
Worked Example 1 — Syllogism (all, some and possibility)
Statements: All pens are tools. Some tools are metal.
Conclusions: I. Some pens are metal. II. Some metal are tools. III. It is possible that some pens are metal.
Solution. The middle term "tools" appears as a whole group in the first statement but only as part of the group in the second. The "metal" tools might be entirely different from the pens, so I does not follow. II follows because "Some tools are metal" can be reversed. III holds because no statement forbids pens being metal, so the possibility stays open.
Answer: Only II and III follow.
Worked Example 2 — Syllogism ("only" wording)
Statements: Only teachers are mentors. No teacher is a clerk.
Conclusions: I. No mentor is a clerk. II. Some clerks are mentors.
Solution. "Only teachers are mentors" means every mentor is a teacher, written as All mentors are teachers. It does not say that every teacher is a mentor, and it adds no extra "isolation" condition. Combine it with "No teacher is a clerk": all mentors lie inside teachers, and teachers have no clerks. So no mentor is a clerk. II contradicts that.
Answer: Only I follows.
A related wording, "Only a few A are B", is commonly read in banking papers as "Some A are B" and "Some A are not B". Confirm the convention in the paper's instructions.
Worked Example 3 — Inequalities (direct, coded and either-or)
Part (a). Statement: P ≥ Q > R = S ≤ T.
Conclusions: I. P > S. II. Q > T. III. T ≥ R.
Solution. I: P ≥ Q > R = S gives P > S because one strict sign sits in an unbroken chain. Follows. II: Q and T both lie above or level with R and S, but the chain meets at a valley, so no relation between Q and T is forced. Does not follow. III: R = S ≤ T gives T ≥ R. Follows.
Answer: I and III follow.
Part (b). Symbols: A @ B means A ≥ B; A # B means A > B; A $ B means A = B; A % B means A ≤ B; A & B means A < B.
Statement: P # Q, Q $ R, R % S. Decoded: P > Q = R ≤ S.
Conclusions: I. P > R. II. Q ≤ S. III. P > S. IV. P ≤ S.
Solution. I follows: P > Q = R. II follows: Q = R ≤ S. For P and S the chain meets at a valley, so neither III nor IV follows alone. Yet "P > S" and "P ≤ S" cover every possibility, so exactly one must be true. That is the either-or case.
Answer: I and II follow, and either III or IV follows.
Worked Example 4 — Blood relations (coded)
Symbols: A + B means A is the mother of B; A − B means A is the brother of B; A × B means A is the father of B.
Statement: P + Q − R × S. How is P related to S?
Solution. P is the mother of Q. Q is the brother of R. Under the conventional exam assumption that the siblings share both parents, P is also the mother of R. R is the father of S, so P is the mother of S's father. That makes P S's paternal grandmother.
Answer: Paternal grandmother under the stated shared-parent convention; without that convention, the relationship is not necessarily determined.
Worked Example 5 — Blood relations (uncertain answer)
Question. Pointing to a man, Meera says, "His mother is the only daughter of my grandfather." How is the man related to Meera?
Solution. The question does not say which grandfather. If he is Meera's maternal grandfather, his only daughter is Meera's mother, so the man is her brother. If he is her paternal grandfather, his only daughter is Meera's father's sister, so the man is her cousin.
Answer: Cannot be determined without knowing the side.
This example shows case splitting on a missing fact. When two readings are both allowed and give different results, the correct response is "cannot be determined".
Worked Example 6 — Direction sense
Question. Ravi starts at point O and walks 9 m north. He turns right and walks 12 m. He turns right again and walks 4 m. How far is he from O, and in which direction?
Solution. Take O as (0, 0), east as +x and north as +y. After 9 m north he is at (0, 9). Turning right from north faces east, so 12 m takes him to (12, 9). Turning right from east faces south, so 4 m takes him to (12, 5). Distance = √(12² + 5²) = √169 = 13 m.
Answer: 13 m, towards the north-east of O. O is south-west of Ravi.
Worked Example 7 — Ranking
Question. In a row, Ravi is 12th from the left and Sita is 15th from the right. After they exchange places, Ravi is 22nd from the left. How many people are in the row, and how many stood between them originally?
Solution. After the exchange, Ravi occupies Sita's original seat, so Sita was originally 22nd from the left. She was also 15th from the right, so total = 22 + 15 − 1 = 36. Originally Ravi was at position 12 and Sita at 22, so the number between them is 22 − 12 − 1 = 9.
Answer: 36 people; 9 between them.
Worked Example 8 — Coding-decoding (positional rule)
Question. In a code, PLAN is written as QKBM. How is BOARD written?
Solution. Compare letter by letter. P→Q is +1, L→K is −1, A→B is +1, N→M is −1. The rule alternates +1 and −1 by position. Apply it to BOARD: B+1 = C, O−1 = N, A+1 = B, R−1 = Q, D+1 = E.
Answer: CNBQE.
Worked Example 9 — Number series
Question. Find the next term: 5, 6, 14, 45, 184, ?
Solution. Check differences first: 1, 8, 31, 139. They do not settle into a clear pattern. Try a combined rule: 5×1+1 = 6, 6×2+2 = 14, 14×3+3 = 45, 45×4+4 = 184. The multiplier and the added number rise together, so the next step is 184×5+5.
Answer: 925.
Worked Example 10 — Input-output
Input: 52 17 39 84 26.
Rule. In each step, the smallest number from the part not yet fixed moves to the next position on the left, and the others keep their order. Step I of the machine gives: 17 52 39 84 26.
Question. What is Step II, and how many steps does the whole arrangement need?
Solution. Step I fixes 17. From 52 39 84 26 the smallest is 26, so Step II places 26 next and the rest keep their order: 17 26 52 39 84. Step III places 39: 17 26 39 52 84. That list is fully sorted, so no further step is needed.
Answer: Step II is 17 26 52 39 84; three steps in total.
Worked Example 11 — Data sufficiency (both statements needed)
Question. What is Rahul's age? I. Rahul is 4 years older than Sneha. II. The sum of their ages is 36 years.
Solution. I alone gives only a difference. II alone gives only a sum. Together, with Sneha = S, Rahul = S + 4 and 2S + 4 = 36, so S = 16 and Rahul = 20. The answer is a single value.
Answer: Both statements together are sufficient; neither alone is.
Worked Example 12 — Data sufficiency (a "No" can be sufficient)
Question. Is P taller than Q? I. Q is taller than R. II. R is taller than P.
Solution. Alone, I says nothing about P. Alone, II says nothing about Q. Together: Q > R > P, so P is definitely not taller than Q. A definite "No" is a complete answer. Sufficiency means a unique answer, not a "Yes".
Answer: Both together are sufficient.
How to Solve Seating Arrangements and Puzzles
Puzzles reward a fixed procedure, and this part of reasoning preparation for competitive exams improves fastest when you follow the same steps every time. Candidates who work clue by clue in the order given usually waste time, because early clues are often weak and later clues are strong. Use the following method every time.
- Identify entities. List the people, objects or events.
- Identify variables. Note what must be assigned: seat, floor, day, colour.
- Extract fixed conditions. Mark direct facts such as "G sits in the middle".
- Separate negative constraints. Keep "not next to", "not at an end" aside; they eliminate, not place.
- Choose a representation. Use numbered slots for a row, a ring for a circle, a grid for multiple variables.
- Establish anchor points. Start with the most restricted entity.
- Make direct deductions. Place everything that follows with certainty.
- Split cases when necessary. If a clue gives two possibilities, branch.
- Eliminate contradictions. Close any branch that breaks a clue.
- Complete remaining placements. Fill what the surviving branch forces.
- Verify every original clue. Test the finished arrangement against the written clues.
- Check uniqueness. Ask whether any other arrangement also works.
- Answer the questions.
- Review. Ask whether a faster order of clues existed.
Why this order works. Fixed facts and the most restricted entity remove the most possibilities first, so there are fewer branches to carry. Negative clues only eliminate options, so they are most useful after something has been placed. Verifying every clue at the end catches the slips that a rushed deduction can hide. Splitting a case is safe only when you close it, so every branch must end in a contradiction or in a complete arrangement.
- Read all clues once
- List entities and variables
- Mark fixed facts and anchors
- Does a clue give one placement?
- Place it and re-read the clues
- Does a clue give two options?
- Split into two cases
- Use negative clues to eliminate
- Test each case against remaining clues
- Any case breaks a clue?
- Close that case
- Keep both cases and test with the questions
- Verify all clues and uniqueness
Text explanation: Start with entities and anchor clues, make forced placements, branch when needed, reject contradictions, and verify uniqueness.
Worked Example 13 — Complete linear seating puzzle with case splitting
Question stem. Seven persons, A, B, C, D, E, F and G, sit in a straight row, all facing north. Seats are numbered 1 to 7 from the left end. Conditions:
- G sits exactly in the middle.
- Exactly two persons sit between E and G.
- A sits immediately to the left of G.
- C sits immediately to the right of G.
- F sits immediately to the left of A.
- D sits at one of the two ends.
- E and B are not neighbours.
Representation. Seven empty slots: [1] [2] [3] [4] [5] [6] [7]. Left means towards seat 1.
Deductions.
- Clue 1: G is in the middle seat, so G = 4.
- Clue 3: A is immediately left of G, so A = 3.
- Clue 4: C is immediately right of G, so C = 5.
- Clue 5: F is immediately left of A, so F = 2.
- The seats left are 1, 6 and 7, for B, D and E.
- Clue 2: exactly two persons between E and G (seat 4) means E is at seat 1 or seat 7. Two cases arise.
Case 1: E = 7. B and D take seats 1 and 6. By clue 6, D must be at an end, so D = 1 and B = 6. Then E (7) and B (6) are neighbours, which breaks clue 7. Case 1 is closed.
Case 2: E = 1. B and D take seats 6 and 7. By clue 6, D is at an end, and seat 6 is not an end, so D = 7 and B = 6. E (1) and B (6) are not neighbours, so clue 7 holds.
Final arrangement (seats 1 to 7): E, F, A, G, C, B, D.
All facing north ↑ · Seats increase left to right → Text explanation: Seats 1–7 from left to right: E, F, A, G, C, B, D. G occupies the middle seat 4.
Clue verification.
- G is in seat 4, the middle of seven. ✓
- E is in seat 1, G in seat 4; seats 2 and 3 lie between, so two persons. ✓
- A is in seat 3, immediately left of G in seat 4. ✓
- C is in seat 5, immediately right of G. ✓
- F is in seat 2, immediately left of A in seat 3. ✓
- D is in seat 7, an end. ✓
- E is in seat 1 and B in seat 6, so they are not neighbours. ✓
Uniqueness. The only branching came from clue 2, and Case 1 failed, so this is the only valid arrangement.
Questions. (a) Who sits at the right end? D. (b) How many persons sit between F and C? Two (A and G). (c) Who sits second to the right of A? C (A is in seat 3, so seat 5).
Worked Example 14 — Floor puzzle with case splitting
Question stem. Five persons, J, K, L, M and N, live on different floors of a five-storey building, numbered 1 (lowest) to 5 (top).
- K lives immediately above N.
- M lives on a floor between K's and L's floors (not necessarily adjacent).
- J lives on the top floor.
- Exactly one floor lies between K's floor and L's floor.
Deductions. From clue 3, J = 5. From clue 1, K cannot be on floor 5, so (N, K) can be (1, 2), (2, 3) or (3, 4).
- N = 1, K = 2. L and M take floors 3 and 4. For M to lie between K and L, M = 3 and L = 4. Clue 4: one floor (3) lies between floors 2 and 4. ✓
- N = 2, K = 3. L and M take floors 1 and 4. If L = 4, M = 1 is not between; if L = 1, M = 4 is not between. ✗
- N = 3, K = 4. L and M take floors 1 and 2. M between K and L gives L = 1 and M = 2. Clue 4 needs exactly one floor between floors 4 and 1, but two lie between. ✗
Final arrangement: floor 1 N, floor 2 K, floor 3 M, floor 4 L, floor 5 J.
Text explanation: Floor 5: J; Floor 4: L; Floor 3: M; Floor 2: K; Floor 1: N. M occupies the third floor.
Question. Who lives on floor 3? M.
Notice how clue 4 acted only as an eliminator in the third branch. Keep such "counting" clues for the end.
Adapting the method to other puzzle types
For circular arrangements, fix one person as the reference and describe everyone relative to that person, then watch the direction clue (facing the centre or outside changes left and right). For parallel rows, fix the row first, then the column. For multi-variable puzzles, draw a grid with one row per entity and one column per variable, and mark both confirmed ("✓") and eliminated ("×") cells. For scheduling and distribution puzzles, treat days or groups as slots and apply the same anchor-and-branch approach.
Keep one rule firm: never guess a branch without a plan to close it. If both branches survive, carry both and let the questions decide.
How to Prepare Analytical Reasoning
PREPON's Analytical Reasoning consists of eight topics. Seating, grouping, scheduling, distribution, floor and box puzzles are not part of it; they belong to the arrangement group above. The eight topics all ask you to judge a statement, argument or action against given information, so the core skill is disciplined evaluation. This strand of reasoning preparation for competitive exams rewards careful reading more than speed.
Two rules apply to all eight. Use only the information given, and treat words such as all, only, always and never as strong claims that need strong support.
Worked Example 15 — Statements & Conclusions
Statement: A municipal corporation announced that rooftop rainwater-harvesting systems will be compulsory for all new buildings above 300 square metres from next year.
Conclusions: I. Existing buildings will not have to install such systems. II. A new 250-square-metre building is not required to install one under this announcement.
Solution. The statement is silent about existing buildings, so I may or may not be true; it does not follow. II follows directly from the 300-square-metre threshold.
Answer: Only II follows.
Worked Example 16 — Statements & Assumptions
Statement: A company has introduced a four-day working week for its design team to reduce staff turnover.
Assumptions: I. A shorter working week can make employees more likely to stay. II. The design team has higher turnover than all other teams.
Solution. The policy only makes sense if I is believed, so I is implicit. II is an extra claim the decision does not need.
Answer: Only I is implicit.
Worked Example 17 — Statements & Arguments
Statement: Should schools introduce a daily 20-minute reading period?
Arguments: I. Yes, regular reading builds vocabulary and concentration. II. No, because some students prefer sports.
Solution. By one widely used convention (check the paper's own instructions), a strong argument is relevant, important and supported by a general reason. I names a general educational benefit directly tied to the proposal. II is a personal preference, and a short period does not prevent sport.
Answer: Only I is strong.
Worked Example 18 — Courses of Action
Problem: Residents report that streetlights on a main road have been off for a week, and two minor accidents have occurred.
Courses: I. The municipal authority should inspect and repair the lights promptly. II. Residents should be banned from using the road at night.
Solution. A sound course of action is practical, directly addresses the cause and avoids creating a bigger problem. I does that. II punishes users and does not fix the fault.
Answer: Only I follows.
Worked Example 19 — Assertions & Reasons
Assertion (A): Trees are often planted along busy city roads. Reason (R): Trees can absorb some air pollutants and provide shade.
Options: (a) Both true, and R explains A. (b) Both true, but R does not explain A. (c) A true, R false. (d) A false, R true. (e) Both false.
Solution. Both statements are accepted as true for this illustration. The reason names benefits that explain why such planting is done. A reason that merely sits beside the assertion without explaining it, such as "trees grow slowly", would give option (b).
Answer: (a).
Worked Example 20 — Causes & Effects
Statement I: Onion prices rose sharply in the city. Statement II: Heavy rain damaged standing crops in the main onion-growing region last month.
Solution. Damaged crops reduce supply, and lower supply tends to push prices up, so II is the more plausible cause and I its effect. The reverse reading does not make sense, because a price rise does not damage crops. Cause-and-effect questions ask for the most plausible link in the given facts. They do not prove that nothing else contributed.
Answer: II is the cause and I is its effect (the most plausible reading).
Worked Example 21 — Truth Verification
Truth-teller and liar puzzles are a standard way to practise checking claims for consistency. A, B and C each speak. A says, "B is lying." B says, "C is lying." C says, "A and B are both lying." Each person is either always truthful or always lying.
Solution. Suppose C is truthful. Then A and B both lie. If A lies, B is truthful, which contradicts B lying. So C lies. C's claim "A and B are both lying" is false, so at least one of them tells the truth. B says C lies, and C does lie, so B is truthful. A says "B is lying", which is false, so A lies.
Check. A (liar) says B lies; B is truthful, so A's statement is false ✓. B (truthful) says C lies ✓. C (liar) says both lie; B is truthful, so it is false ✓. No other assignment survives.
Answer: Only B tells the truth.
Worked Example 22 — Verbal Deductions
Conditional statements are a standard way to practise drawing necessary conclusions from words. Statement: If a train is delayed, the connecting bus waits. The connecting bus did not wait.
Conclusions: I. The train was not delayed. II. The train was delayed.
Solution. The first statement says delay leads to waiting. The bus did not wait, so delay cannot have happened (the contrapositive). I follows; II contradicts it. Be careful with the reverse: "The bus waited" would not prove the train was delayed, because the bus could wait for other reasons.
Answer: Only I follows.
How to Prepare Non-Verbal Reasoning
Non-verbal reasoning questions use figures instead of words, and in reasoning preparation for competitive exams this block is easy to postpone, so schedule it explicitly. The skill is to describe a change in plain language, then apply that same change elsewhere. Practise saying "one shape rotates 90° clockwise and a dot moves one corner to the left" rather than staring at the options.
Core transformations to learn. Rotation (note the angle and direction), reflection (mirror image flips left and right; water image flips top and bottom), translation, addition or removal of elements, and shading or colour changes. In a series, test each element separately: position, count, size, shading, orientation.
Symmetry. Count lines of symmetry and check whether a figure looks the same after a half turn. Shapes with rotational symmetry repeat after a fraction of a full turn.
A reminder about text. A written description cannot fully replace a diagram. The diagram specifications below tell an editor or designer what figures to draw for each example.
Worked Example 23 — Mirror image of a clock
Question. A clock shows 3:20. What time does its image show when the clock is reflected left to right, as in a vertical mirror?
Solution. Use the rule: mirror time = 11:60 − actual time. 11:60 − 3:20 = 8:40. Check the picture: at 3:20 the hour hand is just past 3 and the minute hand is on 4. Flipped left-right, they appear just before 9 and on 8, which reads 8:40.
Answer: 8:40.
Actual: 3:20 Reflection: 8:40 Text explanation: Actual hands at 100° and 120° clockwise from 12 reflect to 260° and 240°. 3:20 becomes 8:40.
Diagram specification: two round analogue clock faces of equal size, each with numerals 1–12 and two hands. Left face: hour hand at 100° and minute hand at 120°, both measured clockwise from 12 (3:20). Right face: the exact left-right reflection, with the hour hand at 260° and the minute hand at 240° (8:40). Label the left face "Actual clock" and the right face "Mirror image", and draw a vertical dashed mirror line between them.
Worked Example 24 — Cube with colours (complete configuration)
Question. One cube has its six faces painted red, blue, green, white, yellow and orange, one colour per face. Two views of the same cube are given. Both views are taken from the same viewing position, so each shows the top, front and right faces, and the red face is on top in both. In View 1, the front face is blue and the right face is green. In View 2, the front face is green and the right face is white. Which colour is opposite blue?
Solution. Around the red top, the four side faces form a ring. Seen from above, the sequence moving clockwise from the right face to the front face is: View 1: green then blue. View 2: white then green. So the ring reads white → green → blue → (fourth face). Opposite faces in the ring are two places apart. White and blue are two places apart.
Check. The remaining ring face is opposite green, and the bottom face is opposite red, so the fourth face and the bottom are yellow and orange in some order. Nothing in the given views changes the answer for blue.
Answer: White.
Visible side-face sequence: WHITE → GREEN → BLUE → fourth face. Opposite pair: WHITE ↔ BLUE. Text explanation: Both views have red on top. Green appears between white and blue around the side-face ring. White is opposite blue.
Diagram specification: two isometric cubes drawn from the same front-top-right viewpoint, each showing three faces. View 1: top red, front blue, right green. View 2: top red, front green, right white. Fill each visible face with a flat colour and print its colour name in the face to support colour-blind readers. Hidden faces are not drawn. Caption: "Same cube, same viewing position; red is on top in both views." Place the two cubes side by side with the labels "View 1" and "View 2".
Worked Example 25 — Paper folding and punching
Question. A square sheet is folded in half along its vertical midline, then folded in half again along its horizontal midline, giving a small square of four layers. One small hole is punched at the centre of this small square. How many holes appear when the sheet is fully unfolded, and where?
Solution. The small square equals one quarter of the original sheet. The punched centre lies at the centre of that quarter. Each of the four layers is a different quarter, and unfolding reflects the hole across each fold line. That produces one hole at the centre of each quadrant.
Answer: Four holes, one at the centre of each quadrant.
1. Open sheetNo holes yet 2. Fold verticallyTwo layers 3. Fold horizontallyFour layers; one punch 4. UnfoldFour holes, one per quadrant Text explanation: Fold the square vertically, then horizontally. One punch through four layers produces four holes, one in the centre of each quadrant.
Diagram specification: four panels in a row, left to right. Panel 1: a plain square sheet with a vertical dashed fold line through its midpoint. Panel 2: the half-folded rectangle (left half folded onto the right), with a horizontal dashed fold line through its midpoint. Panel 3: the quarter-sized folded square with a small filled circle at its exact centre, labelled "punch". Panel 4: the fully unfolded square with the two fold lines dashed and four small filled circles, one at the centre of each quadrant (at one-quarter and three-quarters of the width and height). Use arrows between panels.
Practice routine for non-verbal reasoning. Do ten to fifteen figures a day, and for every wrong answer redraw the figure and write the rule in one sentence. Revisit the same figure two days later to check that the rule sticks. For cubes and dice, always write down the complete configuration before applying any shortcut, since face-orientation shortcuts break when two views share only one face.
Banking Prelims vs Mains: How Should Reasoning Preparation Change?
Banking Prelims and Mains test the same subject but ask for different habits. Reasoning preparation for competitive exams in this family therefore has to be staged rather than flat. Prelims is a screening round with a short time window per section. Mains has longer sets and more room for reasoning depth, so it punishes weak foundations more severely.
What the SBI PO 2026 notice states
The SBI PO 2026 advertisement gives Reasoning Ability 30 questions in 20 minutes in the Preliminary Examination, with separate timing for each section and no sectional cut-off. The Main Examination has a Reasoning & Computer Aptitude section of 40 questions, 60 marks and 50 minutes, within an objective paper of 170 questions, 200 marks and three hours. Each Main section must be cleared individually, and the cut-offs are decided by the Bank. Wrong answers carry a penalty of one-fourth of the marks assigned to that question.
Because the Main section combines Reasoning and Computer Aptitude questions, the notice does not tell you how much of the 50 minutes belongs to reasoning alone. Do not invent a split.
How preparation should change
| Preparation area | Prelims emphasis (editorial guidance) | Mains emphasis (editorial guidance) |
|---|---|---|
| Foundations | Fast, accurate standard topics | Same topics at greater depth; fewer shortcuts that fail on variants |
| Constraint size | Moderate clue sets | Larger sets with more entities and more variables |
| Question selection | Pick quick wins first; skip stubborn sets early | Judge whether a set will resolve before investing time |
| Conditional reasoning | Occasional | Practise “if … then” and “only if” structures deliberately |
| Time management | Short window; little recovery from a lost set | Longer window; a lost set can still be absorbed if detected early |
| Sectional tests | Timed to the notified section length | Timed to the notified section length, including the other subject sharing the paper |
The right-hand column is teaching guidance, not an official statement about question difficulty.
A sensible sequence
Build foundations and standard puzzles for Prelims first, because these also form the base for Mains. After Prelims-level accuracy is steady, add larger puzzles (eight or more entities, two or three variables), conditional puzzles and mixed sets. Keep a weekly Prelims-style timed section running while you do this, so that speed does not decay. In the final weeks, switch to full Main-pattern sections that include Computer Aptitude questions, since the real section shares the clock.
Never let Mains preparation erase Prelims practice. A strong Mains plan does nothing for a candidate who does not clear the screening round.
SSC and Railway Reasoning Preparation
SSC and Railway papers cover a wider spread of question types than a typical Banking puzzle-heavy plan. That is why Banking preparation alone does not automatically cover all SSC reasoning formats, and why reasoning preparation for competitive exams has to widen beyond puzzles here. Candidates who built their skills around seating arrangements often find short verbal and figure-based questions unfamiliar and time-consuming.
What to add beyond a Banking plan
- Verbal reasoning. Analogies, classification, series, coding-decoding and relationships appear in many Railway syllabus lists and are commonly practised for SSC.
- Symbolic operations. The NTPC CEN 05/2024 syllabus lists "mathematical operations". Learn BODMAS-style symbol substitution and practise it until you can do it without writing every step.
- Non-verbal reasoning. Build a separate daily block for figure series, mirror and water images, embedded figures, counting figures and paper folding. Do not assume the paper will have a fixed number of such questions; check the notice.
- Statement-based questions. The CEN 05/2024 list includes statement–conclusion and statement–courses of action, which fall in PREPON's Analytical Reasoning group.
- Maps, graphs and decision making. These also appear in that Railway list and need their own practice.
Timing on the verified SSC CGL 2026 sections
SSC CGL 2026 Tier-I has 25 Reasoning questions in 15 minutes, which is about 36 seconds per question if all are attempted. Tier-II Paper-I Reasoning has 30 questions in 30 minutes, about one minute each. Those are arithmetic averages, not targets. Some questions deserve four seconds and some deserve ninety. The notice also gives Mathematical Abilities its own 30-minute timer within Section-I, so Reasoning's 30 minutes do not borrow from it. Source: SSC CGL 2026 notice.
Topic switching
SSC and Railway sections change question type every few seconds. Train for this by practising mixed sets of ten questions drawn from five different topics, rather than twenty questions from one topic. Switching costs time, and only mixed practice measures that cost.
Railway-specific caution
Reasoning preparation for competitive exams must follow each Railway post’s current notification rather than a generic exam label.
Railway recruitment covers many posts and cycles. Confirm the syllabus of your own post and cycle in its official notice. Use the RRB notice index to find the right document, and avoid applying NTPC patterns to other posts.
How to Improve Reasoning Speed and Accuracy
In reasoning preparation for competitive exams, speed is a by-product of recognition. Candidates who push for speed before they understand a method usually become fast at making errors. Follow this sequence.
- Concept mastery. Solve questions untimed until you can explain each step aloud. Move on only when two consecutive sets are fully correct.
- Recognition. Learn the signature of each question type. A chain with "≥" and "<" signs is an inequality; "facing the centre" signals a circular arrangement. Recognition decides which method you start.
- Diagram efficiency. Use the lightest representation that works. A row needs numbered slots, not a full drawing. Write initials, not names. Mark confirmed placements differently from tentative ones.
- Elimination. For multiple-choice items, test options against the strongest clue first. For arrangements, read the questions before finishing the whole puzzle when a question needs only one deduction.
- Time management. Practise setting a soft time limit per question type and leaving the question when you pass it. Use the notified section time, not a guess.
- Question-selection strategy. Do a first pass that attempts questions you can start within a few seconds. Return to harder sets afterwards if the exam's navigation rules allow.
- Accuracy tracking. Record attempts, correct answers and time for every test. Accuracy is correct answers divided by attempted answers; track it separately from your score.
- Error reduction. Study the error categories, not the individual questions. If most errors are misreading, slow down on reading and speed up on method.
On targets. No official body publishes universal speed or accuracy targets. Set your own baseline from a diagnostic test, then aim for steady improvement at the same difficulty, and raise the difficulty only when accuracy holds.
When a shortcut is unsafe
A shortcut is a compressed version of a method, and it holds only under the conditions in which it was derived. Check these conditions before relying on a trick.
- Clock mirror formula (11:60 − time). Safe for a standard analogue clock reflected left to right. It does not apply to a water image (top-bottom reflection) or to a clock with an unusual face.
- Rank formula (left + right − 1). Safe when both ranks refer to the same row. Unsafe if the ranks come from different groups or if a person is counted twice for another reason.
- Peak-and-valley rule in inequalities. Safe only after every coded symbol has been decoded and every sign (≥ against >) is noted.
- "Some + Some gives nothing" in syllogisms. Safe as a warning, but check the paper's convention and any "possibility" wording before discarding a conclusion.
- Opposite-face rules for dice and cubes. Unsafe unless you know which faces are shown in each view. Write out the complete configuration first.
- Guessing after eliminating options. Safe only when the expected gain is positive under your exam's real penalty, and it remains an average, not a guarantee.
When a shortcut gives a different answer from the full method on a practice question, trust the full method and log the case.
How to Use Previous-Year Questions
Previous-year questions (PYQs) anchor reasoning preparation for competitive exams in real papers, but only if you know what kind of PYQ you are holding. Sort every paper into one of four categories before you use it.
| Source type | What it is | How far to trust it |
|---|---|---|
| Official released paper | Question paper or answer key published by the recruiting authority | Highest; use for pattern and difficulty |
| Official sample questions | Questions the authority provides as examples | High for format; may not show real difficulty |
| Reconstructed memory-based paper | Questions recalled by candidates after the exam | Moderate; may contain errors or omissions, and it is not equivalent to an official paper |
| Coaching-provider analysis | A coaching institute’s interpretation of questions and weights | Treat as opinion; check against official sources |
Use PYQs for three jobs.
Diagnosis. Attempt a PYQ section untimed to see which question types you cannot solve at all. Those gaps are your first priority.
Pattern recognition. After solving, group questions by type and note how each is phrased. You will notice repeated wording such as "exactly" and "not necessarily", which shows what the setter treats as important.
Timed practice. Re-attempt a section against the notified clock. Compare the time you spend per type with how much you got right.
PYQs do not predict the next paper exactly. Topic mix and difficulty change across years, shifts and cycles. Use them to learn how questions are built, then practise original or fresh questions on the same structure. When a source does not name its paper, year and shift, treat any statistics derived from it as unreliable.
The PREPON Reasoning Practice System
The system behind this reasoning preparation for competitive exams has eight stages: Concept → Intuition → Method → Example → Error → Faster Approach → Practice → Assessment. One topic, inequalities, runs through every stage below so you can see how they connect.
1. Concept. State what the topic is and its rules. Concept: an inequality chain such as P ≥ Q > R = S ≤ T compares quantities through symbols; a relation between two ends is certain only if one unbroken chain links them in one direction.
2. Intuition. Explain it in everyday terms. Intuition: think of heights. If P is taller than Q and Q is taller than R, P is certainly taller than R. If Q and T are both taller than R, nothing tells you which of Q or T is taller.
3. Method. Write the procedure. Method: rewrite all statements into one chain; mark peaks and valleys; for a conclusion, check whether a single direction links its two ends; check strictness (≥ against >).
4. Example. Solve a complete item with the method (see Worked Example 3).
5. Error. Record where candidates go wrong. Error: concluding Q > T because both are "bigger than R".
6. Faster Approach. Replace the slow step with a quicker one. Faster approach: instead of rewriting the full chain for each conclusion, mark the two end-variables, trace once from one to the other and stop if you meet a valley.
7. Practice. Schedule varied practice. Practice: ten direct inequalities, then ten coded ones, then ten with either-or conclusions, with the answer reviewed after each ten.
8. Assessment. Test under realistic conditions. Assessment: a timed set of eight mixed inequality questions, with accuracy and time logged in your error log; repeat in a week.
Apply all eight stages to each topic. Skipping from Concept to Practice is why many candidates stay slow.
How to Analyse Reasoning Mock Tests
In reasoning preparation for competitive exams, a mock test is only useful if you convert it into specific changes in what you do next. Many candidates look at the score, feel pleased or upset, and take another mock. Use the steps below within a day of each test.
Step 1: Topic-level performance
| Topic or question type | Attempted | Correct | Wrong | Left | Time spent | Accuracy | Notes |
|---|---|---|---|---|---|---|---|
| Syllogisms | |||||||
| Inequalities | |||||||
| Seating arrangement set | |||||||
| Floor/box puzzle set | |||||||
| Analytical Reasoning | |||||||
| Non-verbal |
Compare topics, not totals. A low total can hide one weak topic and several strong ones.
Step 2: Classify every wrong answer
- Concept gap: you did not know the rule.
- Misreading: you misread a clue or a question.
- Assumption: you used a fact that was not given.
- Calculation or drawing slip: the method was right, the execution was wrong.
- Time pressure: you rushed or guessed.
Step 3: Time-loss analysis
List the three questions or sets that used the most time, and note whether the time was productive. A set that took eleven minutes and returned five correct answers is different from one that took eleven minutes and returned none.
Step 4: Puzzle-abandonment analysis
For each set you skipped or abandoned, note why. Was it unfamiliar? Was it too long? Did you start with a weak clue? Abandoning the right set early is a skill; abandoning every hard set is avoidance.
Step 5: Guessing analysis
Guessing is a numbers question. If a question has n options and each wrong answer costs a fraction p of its marks, the expected gain from a blind guess is 1/n − ((n − 1)/n) × p, in units of the question's marks. With five options and a one-fourth penalty, this is 0.2 − 0.2 = 0. If you can eliminate two options, three remain and the expected gain is 1/3 − (2/3)(1/4) = about +0.17.
Read your own exam's option count and penalty; SBI states a penalty of one-fourth of the marks for the question in its 2026 advertisement, and SSC states different deductions in its own notice.
Expected gain is an average over many questions, not a promise about any single guess: one guess either gains the full mark or loses the penalty. If you are unsure of the option count or the penalty, do not rely on the calculation.
Step 6: Corrective action and retest
For each weak topic, write one corrective action (for example, "redo twelve blood-relation questions using a family tree") and a retest date. Do not move to the next mock until the previous one has been fully analysed.
Text explanation: Diagnose topic → classify the error → check time loss → practise the correction → retest and repeat if needed.
Illustrative example of corrective action. Suppose a sectional mock shows three inequality questions wrong, all labelled "assumption", and one floor puzzle abandoned after seven minutes. The specific actions are: redo ten coded inequalities, marking peaks and valleys before checking any conclusion; set a personal soft time limit for floor puzzles and note whether the limit was kept; and retest both on a named date five days later. These numbers are invented for illustration and are not benchmarks.
- Take timed reasoning mock
- Record scores per topic
- Classify each wrong answer
- Main cause?
- Relearn topic; redo untimed set
- Add a reading checklist; slow first read
- Practise question selection; set soft time limits
- Schedule retest in 5 to 7 days
- Update error log
Build Your Reasoning Error Log
An error log turns each mistake into a recorded cause and a scheduled retest, which makes it a core habit in reasoning preparation for competitive exams. Keep it in a spreadsheet or notebook and update it the same day as each test or practice session.
| Column | What to record |
|---|---|
| Date | When you attempted the question |
| Exam | Exam or exam-style pattern you were practising |
| Test | Mock name or source |
| Topic | For example, Inequalities |
| Question type | For example, coded inequality with either-or |
| Difficulty | Easy, medium or hard (your own judgement) |
| Attempt status | Correct, wrong, left, or guessed |
| Time spent | In minutes or seconds |
| Error category | Concept gap, misreading, assumption, slip, time pressure |
| Root cause | One sentence on why the error happened |
| Correction | The rule or step that fixes it |
| Reattempt date | When you will try a similar question |
| Reattempt result | Correct, wrong or skipped |
A completed example
| Field | Entry |
|---|---|
| Date | 12 October 2026 |
| Exam | SBI PO Prelims pattern |
| Test | Sectional Mock 4 |
| Topic | Inequalities |
| Question type | Coded inequality with either-or |
| Difficulty | Medium |
| Attempt status | Wrong |
| Time spent | 1 min 40 s |
| Error category | Assumption |
| Root cause | Concluded P > S from “P > Q = R ≤ S” without noting the chain meets at a valley |
| Correction | Mark peaks and valleys before checking any conclusion; test the either-or pair |
| Reattempt date | 15 October 2026 |
| Reattempt result | Correct (1 min 05 s) |
How to use the log. Once a week, count entries by error category and by topic. If one category holds most of the entries, change your behaviour for that category before doing more practice. If a question is wrong twice, move it to a "stubborn" list and re-teach the concept rather than redoing the question.
A 30-Day Reasoning Preparation Plan
This is an editorial planning model, not an official schedule. It treats reasoning preparation for competitive exams as a sharpening exercise for candidates who already have reasonable foundations. It guarantees no score; edit it to fit your gaps. Adjust the daily volume to your own available time.
| Week | Objective | Core activities | Check at week end |
|---|---|---|---|
| 1 | Consolidate foundations | Take a diagnostic section. Revise syllogisms, inequalities, blood relations, direction sense, ranking. Start the error log. Do 10 minutes of non-verbal daily | Untimed set accuracy; error-log categories |
| 2 | Pattern topics and linear puzzles | Coding-decoding, series, input-output, data sufficiency. Linear arrangements with case splitting | First sectional test; compare with diagnostic |
| 3 | Advanced structures and Analytical Reasoning | Circular, parallel-row, floor and box puzzles. The eight Analytical Reasoning topics. Mixed sets | Two sectional tests; topic table |
| 4 | Test conditions and revision | Section-length tests in your notified pattern, PYQ sections, error-log retests, final revision of stubborn items | Full section under real timing; retest results |
Exam adaptations. For Banking Prelims, weight puzzles and short sets in Weeks 2 to 4. For SSC, move non-verbal and verbal reasoning from daily blocks into half of the practice time. For Railways, widen the topic list to the notice's syllabus and do not skip maps, graphs or decision making.
A 60-Day Reasoning Preparation Plan
This is an editorial planning model for reasoning preparation for competitive exams when foundations are moderate. It guarantees no outcome and can be edited freely. It adds time for conceptual revision and for advanced practice before test-heavy weeks.
| Days | Objective | Core activities | Check |
|---|---|---|---|
| 1–10 | Concept revision | Re-learn Levels 0 to 2 topics with the eight-stage system; log errors | Two consecutive clean untimed sets per topic |
| 11–25 | New and weaker topics | Input-output, data sufficiency, coded syllogisms, linear and circular arrangements | One sectional test per week |
| 26–40 | Advanced practice | Parallel rows, mixed directions, floor and box, scheduling; Analytical Reasoning; non-verbal blocks | Puzzle completion and abandonment notes |
| 41–55 | Mock-led improvement | Section-length mocks, PYQ sections by source type, mock analysis within 24 hours | Trend in accuracy and time-loss |
| 56–60 | Final consolidation | Revise the error log and stubborn list; one last timed section; light practice only | Readiness checklist (see FAQs) |
Principle. The Day 41 to 55 window should contain more analysis than new learning. If a mock reveals a concept gap, go back to the matching stage of the practice system for that topic.
A 90-Day Reasoning Preparation Plan
This is an editorial planning model for beginners starting reasoning preparation for competitive exams from zero. It allows time to learn the foundations before puzzles, a sequence many candidates find steadier than starting with puzzles. It guarantees no outcome and can be edited freely.
| Days | Objective | Core activities | Check |
|---|---|---|---|
| 1–15 | Reading precision and Level 1 topics | Logical wording drills; ranking, direction, blood relations, simple coding, series | Untimed accuracy on each topic |
| 16–30 | Level 2 topics | Inequalities, syllogisms, data sufficiency, input-output; first diagnostic test | Diagnostic table; first error-log review |
| 31–50 | Arrangements and puzzles | Linear, then circular, then parallel rows, then floor and box; case-splitting practice | Puzzle accuracy and time on each type |
| 51–65 | Analytical Reasoning and non-verbal | The eight topics with examples; transformations, mirror and water images, folding, cubes | Topic-wise quizzes; figure rule notes |
| 66–80 | Mixed practice and sectional mocks | Mixed sets of ten; two sectional mocks a week; mock analysis | Error-category counts; trend lines |
| 81–90 | Revision and test conditions | Full sections in notified length; PYQ sections; final error-log retests | Final readiness review |
Daily structure suggestion. Split each session into a short concept or review block, a main practice block and a five-minute error-log update. For working professionals, shorter daily blocks held consistently usually beat occasional long sessions, because reasoning skills depend on repeated recall.
Reasoning Preparation for Competitive Exams: Banking, SSC and Railways Together
Candidates often apply to all three families. A single plan can serve them if you build it as a trunk with three branches, rather than three separate plans.
Common foundation (the trunk). Syllogisms, inequalities, blood relations, direction sense, ranking, coding-decoding, number and alphabet series, data sufficiency, and the eight Analytical Reasoning topics. Many papers across the three families draw on versions of these, so this is a sensible place for early effort. Confirm each notice, because no exam is assumed to test every listed topic.
Banking branch. Advanced arrangements and puzzles, input-output, larger constraint sets, conditional reasoning and Main-pattern sections.
SSC branch. Non-verbal reasoning, analogies and classification, symbolic operations, and speed on short mixed sets.
Railway branch. Whatever the specific notice adds: for example, maps, graphs and decision making in the NTPC CEN 05/2024 syllabus list. Check the list for your own post and cycle.
Example weekly rotation (editorial model)
| Day | Focus | Notes |
|---|---|---|
| Monday | Trunk topic (new or revision) | One topic from the eight-stage system |
| Tuesday | Banking branch | Puzzle set with case-splitting practice |
| Wednesday | SSC branch | Non-verbal block plus a mixed set of ten |
| Thursday | Trunk topic | A different topic; log errors |
| Friday | Railway branch | Topics specific to the notice; statement-based sets |
| Saturday | Sectional test | Use the pattern of your nearest exam |
| Sunday | Analysis and retest | Mock analysis, error-log review, light revision |
No recruiting authority specifies study hours, so this table gives only the order of focus, not a time requirement. Adjust it as your exam dates become clear: when a Banking exam is a month away, give the Banking branch two or three days a week and keep the others short.
Reasoning is one subject within a larger syllabus. For the other subjects, see PREPON's guides to Quantitative Aptitude preparation and English preparation. For awareness-based sections, the Banking Awareness and General Awareness guides cover those topics.
Common Reasoning Preparation Mistakes
These are common patterns in reasoning preparation for competitive exams. They are editorial observations built on the error categories used earlier in this guide, not official statistics.
| # | Mistake | Why it happens | How to correct it |
|---|---|---|---|
| 1 | Starting with advanced puzzles | Puzzles look prestigious | Follow the dependency levels; master Levels 1 and 2 first |
| 2 | Memorising shortcuts without logic | Shortcuts feel fast | Re-derive each shortcut once; know when it breaks |
| 3 | Assuming facts that were not given | The mind fills gaps automatically | Underline given facts; label every extra idea “assumption” |
| 4 | Ignoring negative clues | Positive clues feel more useful | Keep a separate list of “not” clues and use them to eliminate |
| 5 | Never splitting cases | Branching feels risky | Practise two-branch puzzles until it feels routine |
| 6 | Reading every clue in order | Order seems natural | Scan for the most restricted entity first |
| 7 | Drawing heavy diagrams | Neatness feels safer | Use initials and numbered slots only |
| 8 | Not verifying the final arrangement | Time pressure | Check at least the clues used in the questions |
| 9 | Practising only one topic per session | Comfort | Mix topics to train switching |
| 10 | Skipping non-verbal reasoning | It seems less important | Give it a short daily block if your notice includes it |
| 11 | Treating “Some” as “All” in syllogisms | Everyday speech blurs the two | Draw the sets; test every conclusion against them |

Exam-Day Reasoning Strategy
A sound exam-day routine is the final test of reasoning preparation for competitive exams: make decisions consistent with the exam’s actual instructions.
On exam day, reasoning preparation for competitive exams shows up as following decisions you made in practice. Apply the following in order.
Read the section instructions. Check the number of questions, the sectional time and the penalty rule. SBI's notice, for example, shows each section with its own timing, so time saved in one section does not move to another.
Know the navigation rules. SBI's advertisement specifies separate timing for each section, but whether you can leave a question and return to it depends on the exam interface and its instructions. Read your call letter, the instructions screen and any candidate booklet (SBI refers to an "Acquaint Yourself" booklet) instead of relying on what a friend did in another exam. If you cannot return, the second-pass plan below does not apply, and you must decide each question once.
Understand the negative marking. SBI deducts one-fourth of the marks assigned to the question; SSC CGL 2026 states 0.50 mark for a wrong answer in Tier-I and 1 mark in Tier-II Section-I. Both come from the official notices linked above.
Do a first pass for quick starts. Attempt questions where you can begin within a few seconds. Mark longer sets for the second pass.
Skip deliberately. Leave a set when it is not resolving after your planned time. Passing a time limit is a signal, not a failure.
Check diagrams. Before committing an answer from a puzzle, re-read the final clue and test it against your arrangement.
Manage uncertainty. If a question has several possible readings and none is clearly right, choose using the elimination and expected-gain rules from the mock-analysis section.
Guard against overconfidence. Easy-looking questions hide traps, for example a single "only" or "at least". Read the whole stem before marking.

Frequently Asked Questions
What is the best way to start Reasoning preparation?
Start with precise reading of words such as <em>all, some, only</em> and <em>at least</em>, then learn ranking, direction sense, blood relations and simple coding. Take a short untimed diagnostic set in your first week so that you know your starting accuracy. Use the dependency table in this guide to sequence topics instead of starting with puzzles.
Can beginners learn Reasoning without coaching?
Yes, if they follow a structured sequence and analyse mistakes honestly. The method matters more than the setting. Learn each topic's rule, solve examples with the steps visible, practise in graded sets and keep an error log. Coaching can add feedback and discipline, but it does not replace deliberate practice.
Is Banking Reasoning the same as SSC Reasoning?
No. They share a common foundation, but Banking practice leans towards puzzles and arrangements, while SSC includes a broader spread of short verbal and figure-based questions. Check each exam's notice for its syllabus and pattern, and add the missing topics rather than assuming one preparation covers both.
Which Reasoning topics should beginners study first?
Learn precise logical wording first, then ranking, direction sense, blood relations, simple coding and series. These topics are largely independent of each other. Inequalities, syllogisms and data sufficiency come next, followed by arrangements.
How important are seating arrangements for Banking?
They are a central part of most Banking reasoning preparation, but no official source fixes their share of questions. Treat them as important because they build constraint-handling skill that transfers to other puzzles. Avoid any claim that they always form a set percentage of a paper.
How do I improve puzzle-solving accuracy?
Use the fourteen-step method: list entities, mark anchors, separate negative clues, branch on two-option clues, close contradictory branches and verify every clue at the end. Accuracy rises when you check the final arrangement, and drops when you guess a branch without a plan to close it.
Why do I take too long to solve arrangements?
The usual causes are reading clues in the given order, drawing heavy diagrams, hesitating to branch and not recognising puzzle types. Start with the most restricted entity, use initials in numbered slots and practise two-case puzzles. Time your first and second reads separately to see where the delay arises.
What is the difference between Prelims and Mains Reasoning?
In SBI PO 2026, Prelims Reasoning is 30 questions in 20 minutes, while the Main section combines Reasoning and Computer Aptitude in 40 questions, 60 marks and 50 minutes. General teaching experience suggests Mains sets carry more entities and conditions, but check your exam's own notice.
How can I prepare for non-verbal reasoning?
Do a short block daily. For each figure, state the transformation in words, then check every option against that rule. Redraw wrong figures, learn mirror and water image rules, and practise paper folding by actually folding paper once or twice. Revisit each error two days later.
How should I study syllogisms?
Draw circles or write the four statement types, and test each conclusion against all possible set relationships, not just one. Learn the wording differences for "only" and "only a few". Confirm whether the paper treats "All A are B" as implying "Some A are B", because conventions differ.
How can I improve coded inequalities?
Decode the symbols first and write the chain in ordinary signs. Mark peaks and valleys, then test each conclusion by tracing one unbroken direction. For either-or pairs, check that the two conclusions cover all possibilities and that neither follows on its own.
Is Analytical Reasoning different from seating arrangements?
In PREPON's classification, yes. Analytical Reasoning consists of exactly eight topics about evaluating statements, arguments and actions. Seating, grouping, scheduling, distribution, floor and box puzzles belong to a separate arrangement group. An official Railway syllabus may use the term more broadly.
Can one preparation plan cover Banking, SSC and Railways?
Yes, with a common foundation and three branches. The foundation covers topics shared across all three; the branches add Banking puzzles, SSC non-verbal and verbal items, and Railway-specific topics from the relevant notice. Rotate branches through the week and adjust as exam dates approach.
How many hours should I study Reasoning?
No official body prescribes study hours. Choose a daily block you can sustain, for example a short concept session, a main practice block and an error-log update. If you work, shorter regular sessions usually work better than occasional long ones. Increase time only when accuracy shows it is needed.
Are previous-year questions sufficient?
No. They show how questions are framed but cannot cover every variation, and topic mix changes across years. Combine PYQs with fresh practice on the same structures, and sort PYQs by source type: official paper, official sample, memory-based reconstruction or coaching analysis.
When should I start sectional mock tests?
Start once you have covered the main topic groups at a basic level, usually after your first diagnostic and one round of foundation work. Early sectional tests expose gaps; later ones test speed. In the 30-day plan, the first sectional test falls in the second week.
How do I analyse Reasoning mistakes?
Classify each wrong answer as concept gap, misreading, assumption, slip or time pressure. Record the root cause in one sentence and the correction in one line. Once a week, count entries by category and topic, then change the behaviour that produces most of the entries.
What should I do if I cannot solve advanced puzzles?
Return to the representation skills behind them. Solve smaller versions with fewer entities, then add one variable at a time. Practise case splitting on simple puzzles, and compare your representation with a worked solution to see where it differs.
How can I improve Reasoning speed?
Improve recognition first, then trim your method. Use light diagrams, start from the most restricted entity and decide a soft time limit per question type. Practise mixed sets to reduce the switching cost, and measure accuracy alongside speed so that speed gains do not cost marks.
How should I revise before the examination?
Revise from your error log and stubborn list rather than from your full notes. Redo questions you have previously got wrong, re-read the rules for your weakest topics and take one timed section at the notified length. Keep the last few days light.
Should I guess answers when there is negative marking?
Only when the expected gain is favourable, and remember that expected gain is an average over many questions, not a promise for any single guess. With n options and a penalty of p times the marks, a blind guess gains 1/n − ((n−1)/n)p. With five options and a one-fourth penalty this is zero, so eliminating options first makes a guess worthwhile. Check your exam's real option count and penalty.
How should working professionals prepare?
Use fixed short sessions at the same time each day, with one longer weekend block for a sectional test and analysis. Keep a portable error log and review it during short breaks. Choose the 60-day or 90-day model if your foundations are not strong, since a 30-day plan assumes reasonable basics.
How should I use an error log?
Fill it in the same day as the test: topic, error category, root cause, correction and a reattempt date. Review it weekly, group entries by category and set one behavioural change for the next week. Delete nothing; mark each item as resolved only after a correct reattempt.
How do I know I am ready for the reasoning section?
Look for three signs: your accuracy has held steady across several timed sections at the notified length, your error log shows few new categories of mistake, and your weak topics pass their retests. There is no universal numerical threshold, so compare yourself against your own baseline and trend.
Conclusion: Turn Reasoning Practice Into Measurable Improvement
Reasoning preparation for competitive exams improves when practice is organised. Learn the logic behind each topic, use a fixed method for puzzles, check that you read every clue, and analyse each test so that mistakes lead to scheduled corrections. The eight-stage practice system and the error log are the two tools that make progress measurable.
Begin today with a short diagnostic section, set up your error log and choose the 30-, 60- or 90-day model that matches your foundations. Then check your own exam's official notice for its actual pattern and update your plan as dates become clearer.
