You are trapped in a room with 2 doors.

2 people are in the room with you.

1 of them always tells the truth and one of them always lies.

You don’t know who is the liar or who is the truth teller.

They also know which is the right door.

You can ask them only 1 question.

SO WHAT IS THE RIGHT QUESTION?

Thank you Ethan R. for your submission!

What would the other say is the correct door..

Truth teller would be honest and say the wrong door as that is the one the other would say.

The lying person would say the wrong door as well, because he has to lie and say the truth person would select the wrong door.

So you choose the opposite door that the two people chose on.

The right door is the one that isn’t on the left :|

If the riddle implies “One door leads to certain death if opened, and the other one will see you to safety”, then you can ask either person which door the other person would say leads to safety, and then take the other door.

I ask this

“If I asked you ‘are you standing in front of the freedom door?’, would your reply be ‘yes’?”

If you choose the truthful guard, he will give you an honest answer. Enter his door if he says “yes” and enter the other door otherwise.

If you choose the liar, he will lie about what his reply would be. Since that reply is also a lie, the two lies cancel out. Enter his door if he says “yes” and enter the other door otherwise.

“If I asked you ‘are you standing in front of the freedom door?’, would your reply be ‘yes’?”

Ask if the room has doors and windows to work out who is the “truth teller”

Then ask the “truth teller” where the door is

Dah!

Raymond you are the winner!

Ask one of them what the other would say.If you ask the liar he would say the truth teller would say the wrong door but he’s lying.If you ask the truth teller he would say the liar would say the other door.Therefore you would always choose the other door.which way is right?

You must ask one what the other would say is the correct door.
