Circular Seating Arrangement Questions and Answers

Answer: E

Correct answer: None of these

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits two to B’s left and A three to B’s right. D may touch neither B nor H, which leaves only one seat for D once F is placed two seats to D’s left, and E takes the seat beside B. Clockwise the circle reads B → E → H → ? → D → A → F → ?, the two open seats being directly opposite each other. C is fourth to G’s right - which in a circle of eight means simply opposite - so C and G fill those two seats, but which takes which is not fixed.

B’s left is E’s seat, not C’s; H’s left is the undecided seat, not E’s; and F’s left is the other undecided seat, not A’s. That leaves GD, which would hold only if G happened to take the seat beside D - and since C and G may be either way round, that is not established. No pair is certainly of the kind asked for, so the answer is none of these.

Answer: C

Correct answer: F

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits two to B’s left and A three to B’s right. D may touch neither B nor H, which leaves only one seat for D once F is placed two seats to D’s left, and E takes the seat beside B. Clockwise the circle reads B → E → H → ? → D → A → F → ?, the two open seats being directly opposite each other. C is fourth to G’s right - which in a circle of eight means simply opposite - so C and G fill those two seats, but which takes which is not fixed.

Counting four seats to H’s right - anticlockwise - gives E, B, the undecided seat, and then F. The ambiguity does not affect the count.

Answer: E

Correct answer: None of these

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits two to B’s left and A three to B’s right. D may touch neither B nor H, which leaves only one seat for D once F is placed two seats to D’s left, and E takes the seat beside B. Clockwise the circle reads B → E → H → ? → D → A → F → ?, the two open seats being directly opposite each other. C is fourth to G’s right - which in a circle of eight means simply opposite - so C and G fill those two seats, but which takes which is not fixed.

After the exchange, F takes E’s old seat beside B and E takes F’s. Counting two seats to B’s right - anticlockwise - then gives the undecided seat and lands on E. E is not among the choices, so the answer is none of these.

Answer: B

Correct answer: A

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits four to B’s left, opposite him, and F two to H’s left. A is three to C’s left and G two beyond A, which fits the remaining seats in only one way and keeps C clear of F; D and E then take the last two. Clockwise the circle reads B → D → C → E → H → A → F → G.

F’s right is the next seat anticlockwise, and A occupies it. G is on F’s left.

Answer: C

Correct answer: B

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits four to B’s left, opposite him, and F two to H’s left. A is three to C’s left and G two beyond A, which fits the remaining seats in only one way and keeps C clear of F; D and E then take the last two. Clockwise the circle reads B → D → C → E → H → A → F → G.

Counting three seats to A’s left - clockwise - gives F, G and then B.

Answer: D

Correct answer: DB

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits four to B’s left, opposite him, and F two to H’s left. A is three to C’s left and G two beyond A, which fits the remaining seats in only one way and keeps C clear of F; D and E then take the last two. Clockwise the circle reads B → D → C → E → H → A → F → G.

To sit on someone’s immediate left is to occupy the next seat clockwise from them. D occupies exactly that seat with respect to B. In the other pairs the first person sits on the second’s right, or not beside them at all.

Answer: B

Correct answer: HC

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits four to B’s left, opposite him, and F two to H’s left. A is three to C’s left and G two beyond A, which fits the remaining seats in only one way and keeps C clear of F; D and E then take the last two. Clockwise the circle reads B → D → C → E → H → A → F → G.

E sits with C on one side and H on the other, so those two are her neighbours. D and A are each two seats away.

Answer: A

Correct answer: E

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits four to B’s left, opposite him, and F two to H’s left. A is three to C’s left and G two beyond A, which fits the remaining seats in only one way and keeps C clear of F; D and E then take the last two. Clockwise the circle reads B → D → C → E → H → A → F → G.

H’s right is the next seat anticlockwise, and E occupies it. A is on H’s left.

Answer: E

Correct answer: None of these

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; H sits four to B’s left, opposite him, and F two to H’s left. A is three to C’s left and G two beyond A, which fits the remaining seats in only one way and keeps C clear of F; D and E then take the last two. Clockwise the circle reads B → D → C → E → H → A → F → G.

The seat to B’s right belongs to G, who is not among the choices offered - so the answer is none of these. The arrangement is fully determined, so the data are not inadequate.

Answer: A

Correct answer: D

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix B; F sits three to B’s left and H three to B’s right. A may touch neither F nor B, which leaves A only one seat, and C sits opposite her. G, with D two seats to G’s left, then fits in one way only, and E takes the last seat, clear of B as required. Clockwise the circle reads B → D → C → F → E → H → A → G.

B’s left is the next seat clockwise, and D occupies it. G is on B’s right, so there is no doubt between the two.
