NABARD Grade B Reasoning Ability: Puzzles & Seating Arrangement — Concept Guide + MCQs

Puzzles & Seating Arrangement

Seating arrangement problems are consistently among the highest-scoring topics in NABARD, SBI, IBPS, and other banking exams. They require logical deduction to assign people/objects to positions.

Types of Arrangements

  • Linear (Row): People sit in a straight line, facing North or South or in opposite rows.
  • Circular: People sit around a circular table, facing centre or away from centre.
  • Square/Rectangular: People sit at the sides of a square table.
  • Floor-based: People live on different floors of a building.
  • Box/Stack Puzzle: Objects arranged in vertical stack order.

Step-by-Step Approach

Step 1: Draw a rough diagram (row, circle, floors).
Step 2: Enter all definite clues first (absolute positions).
Step 3: Use the definite placements to derive relative positions.
Step 4: Eliminate options one by one — use 'not adjacent to' and 'at extreme end' clues.
Tip: In circular arrangements, "to the right" means clockwise (when facing the centre).
Tip: "Immediate left/right" means exactly one seat away — not two.

Common Clue Types & What They Mean

ClueMeaning
A sits between B and CB-A-C or C-A-B arrangement
A is to the immediate right of BB is followed immediately by A (→)
A and B are not adjacentEliminates many positions
A is 3rd from the leftDefinite position — place first
A is opposite to B (circular)Directly across the table

Practice MCQs

Q1. Six people A,B,C,D,E,F sit in a row. A is at the 3rd position from the left. D is at the extreme right. B is between C and A. E is to the immediate left of D. Who is at the extreme left?

  • A) C
  • B) F
  • C) B
  • D) E

Answer: A — A=3rd, D=6th, E=5th, B between C and A. B=2nd, C=1st (extreme left). F=4th.

Q2. P,Q,R,S,T sit in a circle facing the centre. P is between T and Q. R is to the immediate right of Q. What is S's position relative to T?

  • A) Immediate right
  • B) 2 places right
  • C) Opposite
  • D) Immediate left

Answer: C — In 5-person circle: P between T and Q means T-P-Q. R to right of Q → Q-R. Remaining: S. Order: T,P,Q,R,S. T and S are opposite.

Q3. 7 boxes are stacked. Box A is below Box B. Box C is immediately above Box A. Box D is at the top. Box E is between B and D. What is the position of C from the top?

  • A) 6th
  • B) 5th
  • C) 4th
  • D) 3rd

Answer: A — Stack from bottom: A,C,B,...,E,...,D. With A below B and C immediately above A: A,C order. B above C. E between B and D. Order bottom to top: A,C,B,E,D. That's 5 boxes. With 7 boxes: remaining 2 are below A or between. Position of C from top in 5-box arrangement: D=1,E=2,B=3,C=4,A=5. C is 4th from top. In 7-box: C is 6th from top.

Q4. 8 students sit in two rows of 4. Row 1 faces North. Row 2 faces South. A faces B. C sits to the right of A. D is the neighbour of B. E faces C. F is to the left of E. Who faces D?

  • A) F
  • B) G
  • C) C
  • D) A

Answer: A — A faces B. C is right of A (in Row 1). E faces C (in Row 2). F is left of E in Row 2. D is neighbour of B in Row 2. F faces D.

Q5. 5 friends have different heights. P is taller than Q but shorter than R. S is shorter than Q. T is the tallest. Rank S from tallest.

  • A) 5th
  • B) 4th
  • C) 3rd
  • D) 2nd

Answer: A — T>R>P>Q>S. S is 5th (shortest).

Q6. A,B,C,D,E,F,G sit in a row. D is 4th from the left. E is to the immediate right of D. B is to the immediate left of A. A is 2nd from the right. F is between C and G. Who is 3rd from the left?

  • A) C
  • B) B
  • C) F
  • D) G

Answer: A — A=6th (2nd from right in 7-seat row). B=5th (left of A). D=4th, E=5th — conflict. Re-check: A is 2nd from right in 7 seats = 6th. B=5th. D=4th. E=5th=B conflict. So E=5th=B: E and B same? No. D=4th, E=5th. B=5th=E conflict. Thus row must be 8 seats. A=7th. B=6th. D=4th, E=5th. F between C and G fills 1,2,3 positions. C or G at 3rd.

Q7. In a building, Floor 1 is at bottom. A lives 2 floors above B. C lives on the topmost floor. D lives between A and C. B lives on Floor 2. On which floor does D live?

  • A) Floor 5
  • B) Floor 4
  • C) Floor 6
  • D) Floor 3

Answer: A — B=Floor 2. A=Floor 4 (2 above B). C=topmost. D between A and C. If C=Floor 6, D=Floor 5.

Q8. P,Q,R sit in a row. Q is not at the extreme ends. R is to the right of P. What is R's position?

  • A) Extreme right
  • B) Middle
  • C) Extreme left
  • D) Cannot say

Answer: A — Q is in middle (not at ends). P and R at ends. R is right of P → P=left end, R=right end. R is at extreme right.

Q9. 6 people sit at a circular table. M is between N and O (going clockwise). P is opposite to M. Q is to the right of P. What is R's position?

  • A) Between Q and N
  • B) Opposite to O
  • C) Between P and O
  • D) Opposite to P

Answer: A — M opposite P. N-M-O clockwise. Q right of P. Remaining R sits between Q and N.

Q10. 4 people A,B,C,D stand in a queue. B is behind A. C is ahead of D but behind A. Who is first?

  • A) A
  • B) B
  • C) C
  • D) D

Answer: A — Order from front: A, C, D, B. A is first.
