Riddle: A man casts away on an island. He knows the following.
-there are two tribes of aborigines, one tribe always tells the truth and the second one always lies.
-there is a certain capital town on this island
The man finds a crossroad of one path splitting in two others. One of them leads to the mentioned capital town. There is an aborigine standing on the crossroad and the man doesn't know which tribe he belongs to. He is supposed to show the man the direction to the capital town. Think of only one question the man should ask the aborigine to find the right path.
It is not that hard.
