Brain Teasers
Native or Visitor
Natives lie and visitors tell the truth. I was having lunch with a salesman and I needed to know if he was a native or a visitor. Instead of asking him, I saw a woman beside us. I said "Go ask the woman if she's a native or a visitor". When he came back he said that she was a visitor. From the answer I knew if he was a visitor or a native. Which is he?
Answer
He is a visitor.If she's a visitor, she would be honest and say so. If she's a native, she'd lie and say she's a visitor. So no matter what, we know that she'll say that she's a visitor. NOW for the man. We know that he says that she's a visitor, therefore he MUST be telling the truth and be a visitor. If he were lying, his response (regardless of what the woman is) would be that she is a native. Make sense?

Let's focus on the woman. if she's a visitor, she would be honest and say so. if she's a native, she'd lie and say she's a visitor. So no matter what, we know that she'll say that she's a visitor. NOW for the man. we know that he says that she's a visitor, therefore he MUST be telling the truth and be a visitor. if he were lying, his response (regardless of what the woman is) would be that she is a native. make sense?
hmm put that way it makes more sense, but i must say i was confuzzled.
I got the right answer even though I got mixed up and thought that visitors lie and natives tell the truth. XD So I thought that she would say native no matter what. Therefore I thought he was lying, and therefore a visitor. XD Funny how it still works...
