the first statement is obviously insufficient
the second statement again by itself does not give us anything ... so insufficient
now, combine the 2 statements, in the second statement if we assume y = 2, then we have x< 2y, but the first statement says that x > 2y, so obviously 2 has to be greater than y , so y < 2 .. ans is C |
