If O and P, A and E and B and Q interchange their positions, then who will be the second person to the right of the person who is opposite to the person second of the right of P ?

  • A.D
  • B.A
  • C.E
  • D.O

Answer: B

Correct answer: A

The men face south and the ladies north, so they face each other; a man’s left is east and a lady’s left is west. M is at an end with O next to her right, so M and O take the two westernmost places in the ladies’ row. E faces O, P lies west of Q, and B lies east of D and faces Q - which fixes B and D. C and N are at opposite corners, as are A and M. Reading both rows from west to east: men C, E, D, B, A and ladies M, O, P, Q, N, each man directly facing the lady above him in that list.

After the exchanges, two places to P’s right brings us to B in the ladies’ row; the person facing her is Q, now in the men’s row. Q faces south, so her right is west, and two places that way is A.
