what i ask for any one of them is ques) whether u come with till heaven's door?

then obviously the lier dont answer is " i don't come". but the other person definetly say " i'll come with u" thats enough to know how is the lier and what is the door to heaven. Source: CoolInterview.com

you can ask one of them "if i ask a question,that where does the other door leads, what will be your's and his answer". now if he is telling the truth,then the two answer given by him would be different(ie heaven,hell or hell,heaven)and if he is lying then his answer would same(ie hell,hell or heaven,heaven) Source: CoolInterview.com

Questions is "what kind of doors are these?" will make true one to say true about the doors and layer will lye about the door so we come to know about the door. Source: CoolInterview.com

The question that should be asked should be such that we know the answer of that particular question.Right!! So the most probable one in this case is "What do you think Which is peaceful,Heaven or Hell?". We know Heaven is where peace of soul lies.So we will quickly judge the person who is speaking truth and who is false.

Assume tat the color of the door is black or any color you required. We can ask question to anyone as "Wats the color of the door?". If he replies correctly wat color the door is , then he is the truth teller and another one is lier. Source: CoolInterview.com

The answer is simple. *Frist we will ask one question at anybody(among two),which we have already known. 1)If we ask a question to true person ,the answer would correct. Then we find the true person. 2)If we ask a question to lier, the answer would wrong.Then we find the lier person.

Just simply ask them where are they from .. The good guy will tell the truth .. and the bad guy will say that he comes from the heaven ... :) Source: CoolInterview.com

the question is this is hell? because if u ask to hell doorkeeper he will tell lie. but the heaven will tell yes so we will go inside of heaven. Source: CoolInterview.com
