Q36. You are standing before two doors. One of the path leads to heaven and the other one leads to hell. There are two guardians, one for each door, approaching you. The only thing you know is that one of them always tells the truth and the other always lies, but you don’t know who is the honest one and who is the liar.
You can only ask one question to one of them in order to find the way to heaven. What would be your question?
Simply ask one of them, “which door was he guarding?” if it happens to be the truth teller, then he would point you to the door to heaven and if he were a liar, then also, he would point you to the door to heaven.
