# Choose the Door of Freedom

You are a prisoner in a room with 2 doors and 2 guards. One of the doors will guide you to freedom and behind the other is a hangman –you don’t know which is which.

One of the guards always tells the truth and the other always lies. You don’t know which one is the truth-teller or the liar either.

You have to choose and open one of these doors, but you can only ask a single question to one of the guards.

What do you ask so you can pick the door to freedom?

If I asked which door will lead to freedom, what will the other guard reply?

If the above question is asked to the truth teller, he will say that the liar guard will point you to the death door.

If the above question is asked to the liar guard, he will say a lie and also point to the death door.

In any scenario, both will point to the death door! So take the other door.
