I dont know if anyone already said this but another soultion would be to first ask a question that you already know the answer of. Then you will know who is lying and you still have one question left, so you just ask the other guy what way to go (who you will know if is is lying too).
Q to guy1: what is 1+1?
A: 3
Liar!
Q to guy 2: should i take right or left?
A: left
Thanks!

it seems lke the answers are many and relatively straight forward. you simply ask an objective question of either one (ie is that a tree there? - the liar must say no, the truthsayer must say yes). did i miss something in the question?
Originally posted by PeakiteThe formula for the answer is that you need to somehow ask both of them by asking one of them. This way you know how to modify the answer to get the right one because the liar will be involved no matter which you ask. For example, ask A "If I were to ask B which is the right way to go, what would he say"?

This will cause you to get a lie every time because,
Look, I have already given the answers. There are two alternatives.
1. "If I was to ask you which way to go, what would you say?
Both would give you the correct answer. OR
2. "If I asked the other man which way to go, what would he say?.
In this case both would give the wrong path.
It is interesting how many people didn't read the question properly or assumed it was the same as a similar riddle they had heard. The question clearly indicates that you only have one question in total, and there is absolutely no mention of villiagers.
Congrats again to those who got it.
