Six people E, H, K, M, S and U are seated in a circle facing the centre. U and H are immediate neighbours of M. E is the only person sitting between K and S. H is to the immediate right of S. Who is to the immediate right of U?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → K
For people sitting round a circle and facing the centre, a person’s right is the next seat anticlockwise (as seen from above) and the left is the next seat clockwise.
U and H are both neighbours of M, so the three sit together as U, M, H.
E is the only person between K and S, so these three sit together as K, E, S.
H is to the immediate right of S, so H and S are neighbours: the two groups join at H and S, giving the ring U, M, H, S, E, K.
H must be on S’s right, that is, anticlockwise from S. This fixes the ring as shown below; the last two seats close the circle, so K sits next to U, on U’s right.
