Four of the following five are alike in a certain way based on the given information and so form a group. Which is the one that does not belong to that group?

  • A.F
  • B.C
  • C.E
  • D.H
  • E.G

Answer: B

Correct answer: C

All eight face the centre, so each person’s left is the next seat clockwise and their right the next seat anticlockwise.

The family sorts itself out first. A is the father of G and F, and H is his wife - so H’s husband is A. D is H’s brother, B is H’s mother, E is D’s daughter, and C is G’s child. Then B sits two to A’s left, D immediately to B’s left, and since B may have no female beside her, the remaining male, C, takes the seat on her other side. F is two seats from A, E two to F’s right, and of the last two seats G must take the one away from E.

Clockwise the circle reads A → C → B → D → E → H → F → G, with A, C and D the three men.

F, E, H and G are all female. C, G’s child, is male - which is how he comes to sit beside B, whose neighbours may include no woman - so he is the odd one out.
