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?

How do you know they aren't telling the truth...if the number is 25, 50, or 75 then they are all telling the truth.
