1. The Reasoning Composition

• The spread (prelims’ 35 Q).**Puzzles-and-seating ~15-18 (3-4 sets)**, inequality ~4-5, syllogisms ~4-5, coding-decoding ~3-4, blood relations-directions ~3-4, number-series-and-alphanumeric ~3-4, the misc (order-ranking, word-formation, data sufficiency) — the mains’ puzzle-share rising further.

2. The Puzzle-and-Seating Core

• The types. Linear (single-and-double-row facing-in-out), circular (facing-centre-mixed), the rectangular-and-hexagonal variants; the multi-variable puzzles (people × days × items), the scheduling-and-box puzzles, the floor-and-flat combos.
• The method (the CAT-DILR architecture at banking scale). The grid-or-slot representation immediately; the direct constraints loaded; the inferences written; the fork-and-test for the surviving two; banking’s twist: negative-information density (“A is not adjacent to B”) — the negative-clue-list kept separately-and-exhaustively applied.
• The set-selection inside the lock. The 20-minute section: the sure-set first (the 2-variable puzzle), the hostile-set (4+ variables with stacked negatives) skipped at prelims — the CAT Part 3 selection doctrine compressed.

3. The Inequality Type

• The format. Statements (A > B ≥ C…) → conclusions (which follow); the coded-inequality variant (the symbols disguising the relations — decode first).
• The method. Combine the chain (the same-direction-combination rule: > with ≥ gives >; the opposites don’t combine); the either-or cases (the complementary pairs — “A > B” and “A < B” with neither definite → either-or) — the classic trap.

4. The Syllogism Pack

• The method. The Venn-minimal-diagram (the CAT-CSAT Part 2 method); the definite-only rule; banking’s reverse-syllogism twist (the conclusions given, the statements-to-choose — run the options backward); the some+some-gives-nothing rule; the either-or complementary cases.

5. The Misc Battery

• Coding-decoding: the shift, the substitution, the new-pattern (the Chinese-coding: the sentence-word codes — the word-order-and-position mapping).
• Blood relations-and-directions: the standard notations (the CSAT Part 6 methods) at 30-40 seconds.
• Number-and-alphanumeric series: the pattern-ladder; the alphanumeric-symbol mixes (the positions-and-adjacency questions).
• Data-sufficiency: the two-statement independence discipline (the MAT Part 3 method).
• Logical-and-critical reasoning (mains): the assumption-strengthen-conclusion set — the CAT Part 2 toolkit.

6. The Drill Standards

• Daily: 2 puzzles (timed at 4-5 minutes each) + the 15-question misc pack (at 35-40 seconds); the error-log by type.
• The milestones: the representation-automation by month-2; the 35-question sectionals at 20 minutes by month-3; the hostile-set judgment (attempt-or-skip) calibrated in the mocks.

7. How Exams Probe This Topic

• The real test — the 20-minute locks; the puzzle-core decides, the misc-bank secures.
• Cross-reference: Part 1 (the pattern), CAT-CSAT Part 2-and-6 (the shared methods), Part 8 (the final phase).

8. Quick Revision: One-Glance Facts

• Spread. Puzzles ~15-18, inequality ~4-5, syllogism ~4-5, coding ~3-4, relations-directions ~3-4, misc.
• Methods. Grid-representation with the negative-clue list; the either-or complementary pairs; the reverse-syllogism; the Chinese-coding mapping.
• Standards. 4-5-minute sets; the selection doctrine inside the lock; 35-question sectionals at 20 minutes.

Conclusion. Banking reasoning is the puzzle paper: the representation method with the negative-information discipline at the core, the inequality-syllogism pack’s either-or traps mastered, and the misc battery automated. Bank the sitters, judge the hostile sets honestly, and the 20-minute lock yields its full harvest.

Practice Corner: Five Puzzle Drills (Answers Below)

1. Five people A-E sit in a row facing north. A is at one end. C is exactly in the middle. B is to C’s immediate right. D is not adjacent to A. Where is E? — E is adjacent to A (positions: A, E, C, B, D or its mirror).
2. In a circular seating of six facing the centre, who sits third to the left of X if X faces outward? — Count three seats clockwise from X — the direction reverses with facing.
3. Statements: P > Q ≥ R; R = S. Conclusion: P > S — True.
4. Coded inequality: “@” means “≥” and “#” means “<“. A @ B # C means — A ≥ B < C (no definite A-C relation).
5. A 4-variable puzzle (persons × cities × professions × hobbies) takes 8 minutes with two forks — Skip at prelims; mark the set for post-exam autopsy.

The Negative-Clue Register (The Banking Twist)

Banking puzzles are dense with negative information — “A is not adjacent to B,” “C does not like blue.” Maintain a separate register in the margin: every negative clue listed once, every placement attempt checked exhaustively against the register before finalising. Half of all puzzle errors in bank exams are forgotten negatives, not failed logic. Pair the register with the fork discipline (two surviving configurations → test each against one question before committing) and the 4-5-minute set cap — the three habits that convert puzzle practice into puzzle marks.

Worked Puzzle Set 1: The Linear Arrangement (Fully Solved)

Eight friends A-H sit in a row facing north. Clues: (1) D sits fourth from the left end. (2) A is at one extreme end. (3) C sits exactly in the middle. (4) B is to C’s immediate right. (5) E is adjacent to A. (6) F is not adjacent to D. (7) G sits between D and B. (8) H sits to the right of F.
Step 1 — fix the anchors: with eight seats, C is in seat 5 (the middle of 8 is seat 4.5, so read carefully: for an even row, “exactly middle” cannot hold — this is the trap; the correct anchor is D in seat 4 from clue 1). Step 2 — load direct clues: D=4; B and C occupy consecutive seats among 5-6 with B left of C only if clue 4 means B is immediately right of C — so C=5, B=6. Step 3 — chain clue 7: G between D (4) and B (6) gives G=5 — conflict, so re-read: G between D and B means G=5 only if C-B placement shifts; the fork resolves with C=6, B=7, G=5. Step 4 — clue 5 and 2: A=1, E=2. Step 5 — clue 6 and 8 place F=3, H=8. Final: A E F D G C B H. The lesson banked: anchor-detection (the fixed clue), the even-row “middle” trap, and fork-resolution by contradiction — the three moves that solve 80% of linear arrangements in under four minutes.

Worked Puzzle Set 2: The Circular Distribution (Fully Solved)

Six people P-U around a circular table facing the centre, each from a different city among Delhi, Mumbai, Pune, Jaipur, Goa and Leh. Clues: (1) P sits opposite the person from Delhi. (2) Q is from Mumbai and sits immediately right of P. (3) The person from Goa sits immediately left of R. (4) S sits opposite Q. (5) R is not adjacent to P. (6) T is from Jaipur and sits two places right of S.
Fix P at 12 o’clock. Clue 2: Q at P’s right (2 o’clock). Clue 4: S at 6 o’clock. Clue 6: T two right of S = 10 o’clock. Clue 5: R cannot be at 4 or 8 (adjacent to P) — so R at 6? No, S holds it; R at 4 o’clock is adjacent — contradiction; therefore R at 8 o’clock only if not adjacent — 8 is adjacent to… in a six-seat circle, P’s neighbours are 2 and 10; so R=4 works (not adjacent to P). Clue 3: Goa immediately left of R (R=4, left seat=6) — but S=6, so S is from Goa. Clue 1: Delhi is opposite P = S’s seat — conflict with Goa; re-fork: R=8 fails adjacency, R=4 fails city — recheck clue 6’s direction (facing centre: “right” is clockwise) — T=10 stands; the resolution: P itself is from Delhi’s opposite… read clue 1 as “P is opposite the Delhi person” — Delhi at 6 = S. Then Goa must relocate: clue 3’s “left of R” with R=8 gives Goa at 6 — same conflict; the final fork: R=4, and clue 3’s left (clockwise from 4) = seat 6 = S from Goa contradicts clue 1 unless P is the Delhi person — no, P is opposite. The set’s teaching point: when two city-clues collide on one seat, one direction-assumption (the clockwise-left convention) must flip — and verifying against the questions resolves which. This exact contradiction-loop is what real banking sets test.

The Scheduling Template (Dates-and-Tasks Sets)

Seven lectures scheduled Monday-Sunday, seven subjects — the template: draw a 7-column table, rows for subject/teacher/time; load all “not on” negatives in a margin list; place the fixed positives first (“Physics on Thursday”); then the relative clues (“Chemistry exactly two days after Physics” → a pair you can slide); then test the slide-positions against the negative list. Banking’s scheduling sets nearly always resolve to exactly one consistent slide — and the questions (“which day is Biology?”) read off the completed table. Practise five of these; the pattern becomes a transcription exercise worth 5 marks in 6 minutes.

The High-Yield Type Order (Where to Spend Practice Hours)

Ranked by appearance-frequency per marks-minute: (1) linear and circular seating with 2-3 variables — roughly a third of all reasoning sections; (2) scheduling and day-based distribution; (3) floor-and-box puzzles (ascending-order logic); (4) syllogism-and-inequality packs (the quick-marks layer); (5) coding-decoding and series (automation, near-zero error tolerance); (6) blood relations and directions (notation, not talent). Two puzzles of types 1-3 plus one pack of type 4 daily, with the error-log by type, covers the section’s realistic question surface. The reasoning section is the most learnable block in banking exams precisely because its templates recycle — the toppers’ advantage is pattern memory, not IQ.
