# You are in a room with 2 doors

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 you are in are 2 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 one of the individuals exactly 1 question. 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?

Ask any of the two, “If i ask the other individual which door leads to treasure, what will he say?” Whichever door he points to will have the lion behind. So choose the other door.

ask a general question to one like which is hot fire or ice.based on his answer you will clearly identify who is knight and who is knave.it means if that person is giving right answer then the other person whom you can ask the other one question is knave so he will tell lie and thus ask that person behind which door lion is there and open the same door. But if the person is giving wrong answer to your general question means he is the knave and whom you can ask the other one question is the knight means he will tell the truth .so now you ask behind which door lion is there and open the other door.
