Who are the following two guys?

A: B is a lying monkey. I am human.

B: A is telling the truth.

### Answer

Assume B is not lying. Then, A would be telling the truth, however, A says B lies. Therefore A would be lying, and hence B cannot be telling the truth. This means A is not telling the truth. Hence B is not a lying monkey, rather, he is a lying human. And A is a lying monkey.Hide Answer Show Answer
