Reasoning

Seating Arrangement & Puzzles — Linear, Circular & Floor-Based

Seating arrangement and puzzles dominate the Banking Reasoning section — every IBPS PO, SBI PO, RBI Grade B and Insurance Mains paper has 15–20 marks of these. They are also high-weight in SSC CGL Tier-II and SBI Clerk Mains. The trick is a clean diagram and elimination using definite clues first.

Exam relevance: IBPS PO / SBI PO Prelims: 10–15 marks. Mains: 15–25 marks. SSC CGL Tier-II: 5–8 marks. RRB NTPC: 3–5 marks.

What Makes Puzzles the Highest-Weight Topic in Banking Exams

Seating arrangement and puzzles together form the single largest scoring band in the reasoning section of every banking examination. In an Institute of Banking Personnel Selection Probationary Officer paper, between fifteen and twenty marks out of thirty-five come from puzzle sets. In the State Bank of India Probationary Officer Mains, the share rises further. The reason is straightforward: a well-constructed puzzle requires the candidate to track several variables simultaneously — names, positions, professions, ages, days of the week or floor numbers — and to combine partial clues into a single coherent table. This skill mirrors the work of a banker reconciling accounts or an administrator coordinating a roster, which is why recruitment bodies treat puzzles as an indispensable filter.

An aspirant who learns to dissect a puzzle systematically can attempt three full sets — fifteen questions — in twenty-five minutes with eighty-five-percent accuracy. An aspirant who attempts puzzles intuitively will typically solve only one set in the same time, and often with two errors. The difference between the two is method, not intelligence.

Linear Seating — The Foundation Format

A linear seating arrangement places a fixed number of people, typically six to eight, in a single row. Each person may face north or south, and the directions of left and right reverse depending on which way a particular person is facing. The professional method begins by drawing a long horizontal line on the rough sheet and numbering the positions one to eight from left to right. Beside each position the candidate writes either an upward arrow (facing north) or a downward arrow (facing south) as soon as the direction is established by a clue.

The second discipline is to read every clue once and classify it as either definite or conditional. A definite clue — for example, that A sits at the extreme left — fixes a position immediately. A conditional clue — for example, that B is to the immediate right of C — fixes a relative position but cannot be plotted until C is fixed. The candidate should plot all definite clues first, then loop through the conditional clues until each one becomes plottable. With practice, this loop converges in two or three passes, and the entire arrangement is locked in under three minutes.

Circular and Square Seating — Direction Discipline

Circular seating introduces a critical complication: when people sit around a table facing the centre, the person immediately to their right is on their left in the diagram. When they face outward, the convention reverses. The candidate should write 'facing centre' or 'facing outward' beside the diagram before plotting any name, and then commit to that convention throughout the question. Mixing the two conventions accidentally is the single most common source of error in circular seating.

Square and rectangular arrangements add the further wrinkle that some people sit at corners and others at the middle of sides, with different numbers of immediate neighbours. The professional approach is to mark corner positions with a small filled square and middle positions with a small open square at the start, so that the diagram itself reminds the candidate of who has two neighbours and who has only one direct adjacent seat.

Floor and Box Puzzles — The Vertical Variant

Floor puzzles place a fixed number of people on different floors of a building, while box puzzles stack or arrange boxes by colour, weight or content. Both belong to the same family because the candidate must establish a vertical or sequential order using clues such as 'A lives immediately above B' or 'C lives two floors below D.' The reliable method is to draw a vertical column with the highest floor at the top, number the floors clearly, and then place each definite clue first.

Two specific traps appear repeatedly. First, the phrase 'immediately above' means a difference of one floor, while 'just above' or 'directly above' may mean any number of floors above — the candidate must read carefully. Second, when the puzzle introduces two attributes per person (for example, floor and profession), the candidate must build a two-column table rather than relying on memory. Memory fails under examination pressure; tables do not.

Categorisation Puzzles — Multiple Variables, One Table

The hardest puzzles in banking mains examinations involve five to seven persons and three or four attributes — for instance, a person's name, profession, favourite colour and day of the week on which they were born. The professional method is to draw a single grid with one row per person and one column per attribute, then fill cells gradually as clues are processed. Each clue produces either a positive entry (a definite assignment) or a negative entry (an exclusion such as 'A does not like blue'), and both must be recorded.

The discipline of recording exclusions is what separates expert solvers from intermediate solvers. A correctly noted exclusion eliminates one cell, and a chain of exclusions often forces a unique positive answer in another cell by elimination. Without this discipline, the candidate keeps revisiting the same clues without converging on a solution.

How to Practise Puzzles Effectively

An effective preparation plan covers puzzles in four weeks. The first week focuses entirely on linear seating with one definite clue and three conditional clues per question, building the habit of always plotting definites first. The second week introduces circular seating with the centre-facing or outward-facing convention. The third week adds floor puzzles and one-attribute box puzzles. The fourth week is dedicated to two-attribute and three-attribute categorisation puzzles attempted under timed conditions of seven minutes per set.

By the end of the fourth week, an average aspirant can solve three full sets in twenty-two to twenty-five minutes with accuracy above eighty-five percent. This single performance is sufficient to clear the reasoning sectional cut-off in every major banking examination, and it directly contributes fifteen to eighteen marks to the overall score.

1Linear Seating Arrangement

A linear arrangement places people in a single straight row, typically all facing the same direction (north or south), or two parallel rows facing each other.

Always start with DEFINITE clues — those that fix exact positions or pin down two persons together. Note each person's facing direction. 'Immediate left/right' depends on the facing: in a row facing north, A's right neighbour is the person to A's east. Use elimination grids when information is partial. Common cues: 'second from the right end', 'fourth to the left of P', 'between A and B'.

Examples
  • Six persons A–F sit in a row facing north. A is to the immediate left of B. C is at the right end. → A is to the west of B.
  • If P is fourth from the left and the row has 7 seats → P's left has 3 persons, right has 3 persons.
  • Two rows of 5 persons facing each other — if K is opposite L who is third from left, then K is third from right of his row.
  • 8 persons in a row, S is third from left, T is sixth from left → T is to the right of S, gap = 2 seats.
Exam tip: Always note facing direction at the very start. 'Immediate right' for a person facing south is the OPPOSITE side of the page from someone facing north.

2Circular Seating Arrangement

Circular seating places persons around a circular/round table, facing either the centre or away from it. The arrangement may also be elliptical, square or rectangular with persons at corners and mid-points.

Step 1: identify whether persons face the centre or outside — this swaps left/right. Step 2: draw the circle and mark the table size first (8 / 10 / 12 seats). Step 3: place the most-anchored person and use the 'immediate left/right' cues. For mixed-facing tables, mark each person's individual orientation. Adjacency clues are stronger than directional ones.

Examples
  • 8 persons around a round table facing the centre. A is to the immediate right of B → A sits anticlockwise of B.
  • If facing outside, the rule reverses: A's immediate right is clockwise of A.
  • Square table with 8 persons (4 at corners face outside, 4 at sides face inside): the person between two corner persons is on a side.
  • 10 persons, P is third to the left of Q, Q is opposite R → R is third to the right of P (use the 'opposite' as a fixed bridge).
Exam tip: When the question says 'half face the centre and half face outside', identify each person's facing FIRST. Apply left/right relative to each person's individual facing — not a single global direction.

3Floor-Based & Box Puzzles

Floor puzzles place persons on different floors of a building (usually 5–8 floors). Box puzzles stack labelled boxes one above another. Both are essentially vertical seating arrangements.

Number the floors/boxes from 1 (bottom) to n (top) and mark each clue's relative position with arrows. Watch for keywords: 'immediately above/below', 'two floors above', 'odd-numbered floors', 'just above'. If 'between A and B' appears with no count, both 1 and 2 floors between are possible — keep both cases until a later clue eliminates one.

Examples
  • 8 persons live on floors 1 (bottom) to 8 (top). P lives on floor 3. Q lives 2 floors above P → Q is on floor 5.
  • 5 boxes A–E stacked. C is just above A. B is at the top. D is below E → order top-to-bottom: B, ?, ?, ?, ? → solve by chaining.
  • Floor puzzle: 'Person X lives between Y and Z' with no count → could be 1 or 2 floors between; carry both.
  • If only 2 floors are between P (top) and Q, and P is on floor 6, then Q is on floor 3.
Exam tip: Always start with clues that have an EXACT distance (e.g. 'two floors above'); leave loose clues for later. Loose clues become exact once the framework is built.

Short Tricks & Shortcuts

Use these speed tricks in the exam. Each trick is followed by a worked example so you can verify the shortcut yourself.

Trick 1Pin definite clues first

Sort the clues into definite (fixes a position exactly) and vague (relative). Solve definite clues first; vague clues snap into place once the skeleton is built.

Example: Clue 'A is at the right end' is definite — pin A first. Clue 'B is to the right of C' is vague — apply it later.
Trick 2Direction-aware left/right

For a person facing north, their right is east. For a person facing south, their right is west. ALWAYS verify the facing before applying any 'left/right' clue.

Example: If A faces south and B is to A's right, then B is to A's WEST (not east).
Trick 3Use 'opposite' as a fixed bridge in circles

In a circular table with even seats, 'opposite' fixes a unique pair. Use it to bridge two halves of the puzzle and pivot left/right counts across the centre.

Example: 10-seat round table, P opposite Q, R is third right of P → R is third left of Q.
Trick 4Carry both cases when gap is unknown

When a clue says 'between A and B' WITHOUT specifying the count of persons, carry both possible cases until a later clue rules one out. Do NOT assume.

Example: 5 floors, 'X lives between A (3) and B (?)' — B could be 1 or 5. Wait for the next clue.
Trick 5Floor-puzzle bottom-up numbering

Always number floors 1 = bottom, n = top. 'Above' increases the number; 'below' decreases it. Sketch a vertical column with these numbers before reading the clues.

Example: 8 floors, P on floor 3, Q two floors above → Q on floor 5.

Quick Revision Facts

  • Round table — facing centre: anticlockwise = each person's right.
  • Round table — facing outside: clockwise = each person's right.
  • 8 corners of a square table = 4 corners + 4 mid-side positions.
  • Total left + right + the person himself = total seats. e.g. row of 8: third from left = sixth from right.

Frequently Asked Questions

Draw the framework first (row/circle/floors). Pin DEFINITE clues. Apply VAGUE clues in order of how many cases they leave open. If two cases are possible, run both until one is eliminated.

Each person's left/right depends on THEIR own facing — not a global one. Mark each person's facing at the start and re-apply 'immediate left/right' from that perspective.
