Question

In an island, the natives lie and visitors speak the truth. A man wants to know whether a salesman beside him in a bar is a native or visitor. He asked him to ask a woman beside him whether she is a native or visitor. He replied, "she says she is a visitor". Then he knew that the salesman is a native or visitor. The salesman is in which category, native or visitor?

Answer 1

Answer:  The answer is he is a visitor i.e. he is telling the truth

Reason:

If he was a native i.e. a liar then his answer would would have been "she says she is a native" for both cases because

If she was visitor: she would have said she is a visitor and he would have lied that she is a native

If she was native: she would have lied and again say that she is a visitor and he would have lied that she is a native.
