Who is second to the right of T?
Answer: C
Correct answer: M
Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix K, put P three seats to K’s right and D two to P’s right. Of the ways of placing W with T three seats to W’s right, only one keeps W away from D’s side, and M three to R’s left then falls into place. Clockwise the circle reads K → M → D → T → P → R → W.
Counting two seats to T’s right - anticlockwise - gives D and then M. The arrangement is fully determined, so the data are not inadequate.
