Five friends A, B, C, D and E sit in a row facing North. C sits in the middle. A sits to the immediate right of C. B sits at the extreme left end. D does not sit at either end. Who sits at the extreme right end?
- A) E
- B) A
- C) D
- D) C
Show answer & explanation
Answer: A) E
Number the seats 1 to 5 from left to right (facing North, right is towards seat 5). C is in seat 3, A in seat 4, B in seat 1. D is not at an end, so D takes seat 2, leaving seat 5 for E.
Question 2
Six persons P, Q, R, S, T and U sit around a circular table facing the centre (so each person's left is the clockwise direction and right is the anticlockwise direction). P sits opposite S. Q sits to the immediate left of P. R sits opposite Q. T is not a neighbour of P. Who sits to the immediate right of P?
- A) Q
- B) T
- C) U
- D) R
Show answer & explanation
Answer: C) U
When facing the centre, a person's left is the clockwise neighbour. Put P at seat 0 and number seats clockwise: S at 3, Q at 1, R opposite Q at 4. T and U take seats 2 and 5; seat 5 is next to P, so T is at 2 and U at 5. P's immediate right is the anticlockwise neighbour, seat 5, i.e. U.
Question 3
Seven persons A, B, C, D, E, F and G sit in a row facing North. D is third from the left end. C is to the immediate left of D. G is second to the right of D. B sits between D and G. F is to the immediate right of G. A sits at one of the ends but is not next to F. Who sits at the extreme right end?
- A) A
- B) E
- C) F
- D) G
Show answer & explanation
Answer: B) E
Seats 1 to 7 from the left: D = 3, C = 2, G = 5, B = 4, F = 6. The remaining seats are 1 and 7 for A and E. A at seat 7 would be next to F, so A is at seat 1 and E at seat 7.
Question 4
In a row of 25 students, Rahul is 9th from the left end. What is his position from the right end?
- A) 16th
- B) 18th
- C) 17th
- D) 15th
Show answer & explanation
Answer: C) 17th
Position from right = total − position from left + 1 = 25 − 9 + 1 = 17. Forgetting to add 1 gives 16th.
Question 5
Eight friends sit around a circular table at equal distances, facing the centre. E sits exactly opposite A. How many persons sit between A and E when counted clockwise from A?
- A) 4
- B) 3
- C) 2
- D) 6
Show answer & explanation
Answer: B) 3
With 8 equally spaced seats, the seat opposite is 4 places away. Counting clockwise from A, E is the 4th seat, so there are 3 persons between them (and 3 on the other side as well).
Question 6
Five persons A, B, C, D and E sit around a circular table facing the centre (so each person's left is the clockwise direction and right is the anticlockwise direction). A is second to the left of B. C is to the immediate right of B. D is not adjacent to C. Who sits to the immediate left of A?
- A) E
- B) D
- C) B
- D) C
Show answer & explanation
Answer: A) E
Facing the centre, left is clockwise. Place B at seat 0 (seats numbered clockwise 0 to 4). A, second to the left of B, is at seat 2. C, immediate right of B, is at seat 4. Seats 1 and 3 remain; seat 3 is next to C, so D is at 1 and E at 3. The immediate left (clockwise) of A at seat 2 is seat 3, i.e. E.
Question 7
Six persons J, K, L, M, N and O sit in a row facing North. K sits at the extreme left end. O is fourth to the right of K. L is to the immediate right of O. N is second to the left of O. M is not next to K. Who sits between N and O?
- A) J
- B) L
- C) K
- D) M
Show answer & explanation
Answer: D) M
Seats 1 to 6 from the left: K = 1, O = 5, L = 6, N = 3. Seats 2 and 4 remain for J and M. M is not next to K, so M = 4 and J = 2. The person between N (3) and O (5) is M.
Question 8
In a row of persons facing North, P is 7th from the left and Q is 10th from the right. When P and Q interchange their positions, P becomes 15th from the left. How many persons are there in the row?
- A) 25
- B) 24
- C) 23
- D) 17
Show answer & explanation
Answer: B) 24
After interchange, P occupies Q's original seat, so Q's original seat is 15th from the left and 10th from the right. Total = 15 + 10 − 1 = 24. Forgetting to subtract 1 gives 25, and 7 + 10 = 17 ignores the interchange information.
