Fork In The Road – Logic Question of the day


Fork In The Road - Logic Question

You are traveling down a country lane to a distant village. You reach a fork in the road and find a pair of identical twin sisters standing there.

  • One standing on the road to the village and the other standing on the road to Neverland (of course, you don’t know or see where each road leads).
  • One of the sisters always tells the truth and the other always lies (of course, you don’t know who is lying).
  • Both sisters know where the roads go.

If you are allowed to ask only one question to one of the sisters to find the correct road to the village, what is your question?



This is one of the most famous logic problems which can be solved by using classic logic operations. You may have heard a few variations of this puzzle before (eg. 2 doors – 1 to heaven and 1 to hell) but still, it’s one of the best brain teasers.
There are a few types of logic questions:

  1. Indirect question: “Hello there beauty, what would your sister say if I asked her where this road leads?” The answer is always negated.
  2. Tricky question: “Excuse me, lady, does a truth-telling person stand on the road to the village?” The answer will be YES, if I am asking a truth-teller who is standing at the road to the village, or if I am asking a liar standing again on the same road. So I can go that way. A similar deduction can be made for a negative answer.
  3. Complicated question: “Hey you, what would you say, if I asked you …?” A truth teller is clear, but a liar should lie. However, she is forced by the question to lie two times and thus speak the truth.
