Problem about 3 guys Tom, d**k and harry - One say the truth always , one always lies who is who?

Answer 1

Well there should only be two people for a start. The original question went like this:

There are two identical brothers, one always tells the truth, the other always lies. You're aloud to ask them just one yes or no question,what single question can you ask them that will distingish which one's which?

The answer is: If I asked your brother wether you always tell the truth, what will he say?

The truth teller will say no, the lier will say yes.
