In which of the following pairs is the third person sitting in between the first and the second persons?

  • A.USP
  • B.VRU
  • C.TQW
  • D.WPS
  • E.None of these

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 P; T sits two to P’s left, V three beyond T, W on T’s right and S two beyond W. Q three seats to U’s right then fits the remaining three seats in only one way. Clockwise the circle reads P → W → T → Q → R → V → U → S.

Taking each group in turn: P sits between S and W, not between U and S; U between V and S, not between V and R; W between P and T, not between T and Q; and S between U and P, not between W and P. No group fits, so the answer is none of these.
