If there are two persons in a room and you are also in the room .There are two doors in the room with the condition that at one door a lion is sitting and at another door there is a coin .u have to pass through the door at which there is a coin with the help of the persons which are with you inside the room and condition is that one person is lying and other is speaking truth.what question you should ask from those persons by which you could come out through the gate at which there is a coin .

• I ask any one of them the following question
  
  "What would the other person say the correct door to get a coin?"
  For example, If I ask the truth-teller, then he will show the incorrect door.
  and, If I ask the liar, then he will show again the incorrect door
  So, I could easily find out the correct door to get a coin
