Lets see who figures it out…. April 22, 2009

You are in a room with 2 doors leading out. Behind 1 door is a coffer overflowing with jewels and gold, along with an exit. Behind the other door is an enormous, hungry lion that will pounce on anyone opening the door. You do not know which door leads to the treasure and exit, and which door leads to the lion. In the room, there are 2 other individuals. The first is a knight, who always tells the truth, and a knave, who always lies. Both of these individuals know what is behind each door. You do not know which individual is the knight, or which one is the knave. You may ask each individual exactly 1 question and that question should be same. What should you ask in order to be certain that you will open the door with the coffer behind it, instead of the hungry lion?

get your creative minds thinking…!

I think I have it…. I have gone through several flow charts in my head with different questions and responses … but here’s my solution:

If I ask them “which one would the other responder tell me the lion was behind?”

If it were the knight-he’d point at the jewels (because the lying knave would point to the jewels if asked to point to the lion).

If it were the knave- he’d point at the jewels (because the honest knight would point to the lion if asked to point to the lion, so the lying knave would point to the jewels instead).

Then walk through that door!
