Puzzle of the day
Question:
You’re at a fork in the road and one path leads you to the City of Lies where everyone always lies. And the other path leads you to the City of Truth, where everyone always tells the truth. There’s an old woman at the fork who lives in one of the cities, but you do not know which one. What question could you ask the old woman to find out which path leads to the City of Truth?
Show answer
Answer:
You should ask 'Where do you live?' Someone from the City of Lies will lie, and therefore point to the City of Truth; someone from the City of Truth would tell the truth and also point to the City of Truth.
