Suppose you die and awaken in a room with two doors and one guard at each door. A voice speaks to you and tells you that one door leads to eternity in Heaven and one door leads to an eternity in Hell. You are allowed to approach a guard and ask him a question and only one question that will help you determine which door to choose since the doors are unlabeled and you are unable to look through a door before entering.
However, you are also told that one of the guards ALWAYS lies and one ALWAYS tells the truth, and you cannot know which one is which.
What question do you ask so that, no matter which guard you ask (remember, you CANNOT know which one you are asking), you get an answer that guarantees that you choose the correct door?
Remember, you must choose the door correctly that leads to Heaven.

so how would you identify if the door leads to heaven?
Are you a guard? If he answers "NO", then he is the liar and is most likely guarding the door to hell.
what if the guard who lie post on the door leads to heaven and the guard tells the truth post in the door leads to hell?
There is a guard at each door. Also, for this puzzle/riddle to work properly, it implies that the guard(s) have no prior knowledge.
The question to ask is, simply, this: If I were to ask the other one which door he was guarding, what would his answer be?
The guard who was guarding Heaven's door would know that the the other guard would lie and answer accordingly. The guard who was guarding hell's door, would know that the other would tell the truth and say 'Heaven' but, as he always lies, would answer "Hell". Whatever answer they give would be the door they are guarding.
Does your head hurt now?
i'd ask: what's my name? because i know what my name is i know which one is lieing and which one is telling the truth
so how can you tell in which two doors leads to heaven? You already asked...
I will beat both of them and i will ask
did i beat u ?
the hell guard will say NO
the heaven guard will say YES
