Incorrect information. (Posted on 2002-04-27)

Four people think of a number, and then proceed to each tell you something about it.

A: The number has 2 digits
B: The number is a divisor of 150
C: The number is not 150
D: The number is divisible by 25

Unfortunately, one of these people is not telling the truth. Who is it?

If C is lying, then so is A. So, C cannot be the liar. However, if A is the liar, C isn't necessarily a liar also. This leaves you with A, B, or D to choose to be the liar.
