The question should be "Lie about the door to heaven". The answer from both the liar and the truth speaking person would point to the door of the hell, irrespective of against which gate they are positioned".

The question which can be asked to both is " is the other person saying true if he says this door is to heaven " let door1-heaven door2-hell question to person who says truth always-is the other person saying the truth if he says heaven is door 1 .then his answer will be obvisuly "no" bcoz he says truth and the other person "s answer if asked is that door1 is heaven" his answer will be "yes" .and similarly the same question to person who says false then hi answer will be "no" because he always lies the actually answer when asked to truth person will be "yes" hence it is door1 -heaven if both of them say no to this question asked just test u will get it

The question which can be asked to both is " is the other person saying true if he says this door is to heaven " let door1-heaven door2-hell question to person who says truth always-is the other person saying the truth if he says heaven is door 1 .then his answer will be obvisuly "no" bcoz he says truth and the other person "s answer if asked is that door1 is heaven" his answer will be "yes" .and similarly the same question to person who says false then hi answer will be "no" because he always lies the actually answer when asked to truth person will be "yes" hence it is door1 -heaven if both of them say no to this question asked just test u will get it

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.

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)

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.

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.

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.
