Eight boys, A, B, C, D, E, F, G and H, are sitting around a circular table, facing the centre. A and B are sitting opposite each other. D is sitting second to the right of A. G is sitting second to the right of B. E and H are sitting opposite each other, but E is not an immediate neighbour of A. C is sitting between A and G. How many boys are sitting between F and G, counted from the right of F?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 2
Facing the centre, a person’s right is anticlockwise. Fix A’s seat and place the others around him.
B sits opposite A
D is second to the right of A, and G is second to the right of B
Counting clockwise from A, G is two seats away; C sits between A and G, so C is the seat right after A clockwise
Three seats are left: the seat between G and B, the seat between B and D, and the seat between D and A
E and H sit opposite each other; the only pair of opposite seats among these three is the seat between G and B and the seat between D and A
E is not next to A, so E sits between G and B and H between D and A; F takes the seat between B and D
Clockwise from A the order is A, C, G, E, B, F, D, H
Moving to the right of F (anticlockwise): B, E, then G, so 2 boys (B and E) sit between F and G
