Seven people, P, Q, R, S, T, U and W, are sitting around a circular table, facing the centre. Q sits third to the right of P. T sits second to the left of Q. S sits to the immediate right of Q. W is a neighbour of neither P nor Q. U is a neighbour of T.
Who are the immediate neighbours of W?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → R and S
Facing the centre, left is clockwise and right is anticlockwise. Number the seven seats 0 to 6 clockwise, giving P seat 0.
Q is third to the right of P: three seats anticlockwise, seat 4
T is second to the left of Q: two seats clockwise from Q, seat 6
S is to the immediate right of Q: one seat anticlockwise, seat 3
Seats 1, 2 and 5 are left. Seat 1 is next to P and seat 5 is next to Q, so W is in seat 2
U is next to T (seat 6), so U is in seat 5, and R takes seat 1. Clockwise order: P, R, W, S, Q, U, T
W in seat 2 has R (seat 1) and S (seat 3) on either side: the neighbours are R and S
