Six persons A, B, C, D, E and F are sitting in two rows, three in each. B is not at the end of any row. D is second to the left of A. E, the immediate right of B, is sitting diagonally opposite to D. B is the neighbour of F. Who is facing B?

C

B is not at the end of any row.

∴ B is at middle position.

D is second to the left of A.

E, the immediate right of B, is sitting diagonally opposite to D.

This implies if B and E are sitting in row 1 then D is sitting in row 2.

B is the neighbor of F.

Therefore, above arrangement is the only arrangement but D C A are either on row 1 or row 2 and same is true for F B E.
