Four of the following five are alike based upon their seating arrangements and so form a group. Which is the one that does not belong to that group?

  • A.CH
  • B.FG
  • C.DA
  • D.BE
  • E.GB

Answer: C

Correct answer: DA

Facing the centre, each friend’s left is the next seat clockwise and their right the next seat anticlockwise. Fix E; D sits three to E’s left and A two to D’s left. B is two to G’s right, H three to B’s right and C three to G’s right, so choosing G’s seat fixes three others - and only one choice leaves G clear of E. F takes the seat left over. Clockwise the table reads E → C → B → D → G → A → F → H.

In CH, FG, BE and GB the second person named sits second to the right of the first - two seats anticlockwise. In DA the second person sits two seats the other way, to D’s left, so that pair does not belong.
