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

  • A.EKB
  • B.CHB
  • C.AGC
  • D.FGD
  • E.None of these

Answer: D

Correct answer: FGD

Facing the centre, each person’s left is the next seat clockwise and their right the next seat anticlockwise. Fix C; G sits two to C’s right, B four to G’s left, F four to C’s right, K two to F’s right and A four to K’s right - a single chain that fills six of the nine seats. H three to E’s right then fits the remaining three seats in only one way, leaving D clear of both K and B. Clockwise the circle reads C → H → B → K → E → F → D → G → A.

In FGD the third person named, D, sits directly between the other two, with F on one side and G on the other. In the remaining groups the third person is not between the first two.
