I have one quiz not sure if it is too easy to ask here. You reach to a three way junction. You dont know which way is the right way for you (You have to choose one from 2 ways as you not going to return back). There are 2 people on the road, one never lies whereas the other always lies and there is no way to know who is lier. You can ask only one question with only one of them. How you can get the correct way you need to go?
