You are walking down a trail, and you come to a point where the trail splits. One route goes to a village where everyone always lies. The other route leads to a village where everyone always tells the truth. There is a villager at the intersection. You want to go to the village where everyone tells the truth, but you don’t know if the villager will tell you the truth.

This isn't a math question. But I'll answer:D Ask the villager to point out which road leads to his village. That's the way.

but how do you know if he comes for the one that everyone lies?

OpenStudy (yanasidlinskiy):

Whenever you ask and he tells you the answer, you go the OPPOSITE.

OpenStudy (sheraz12345):

But what if he is speaking the truth

OpenStudy (yanasidlinskiy):

If he's a truthteller he will point out the liars village and Knowing that the other villager would point to the liars village. Therefore He will point to the liars village.

OpenStudy (yanasidlinskiy):

If he's a liar then he knows that the other village will point to the truthteller village. Therefore whether he is a truthteller or a liar it doesn't matter, both have pointed to the liars' village - therefore, GO THE OTHER WAY!!:D

OpenStudy (sheraz12345):
