A brain teaser with a genuine sound & logical answer

Question

You’re in a room that has two identical looking doors; one leads to h**l the other to heaven. You may only open one door. Standing in front of each door is an identical guard. The only difference is that one of these guards tells the truth the other always tells the exact opposite to the truth (it is unknown which guard stands at what door). You may ask a guard one question to determine which door is which. What question do you ask?

First correct answer 10 Pt's. If no one answers correctly, I'll give you it after I receive 30 stars.

Answer 1

I would ask a guard which door leads to Heaven. I would then go to the door opposite of the door they told me goes to Heaven.

Answer 2

i know the answer u ask: does the  person who tells the truth have the door to heaven?

outcomes:

if the person does have access to heaven then

truth he says - yes

lier he says- yes   so u go to that door

if the person doesn't have access to heaven

truth- no

lier- no   so u go to the other door!!

ps saying does the other one have access to heaven is not very effective because if the person does have access:

lier would say yes

truth would say no

doesn't have access;

lier would say no

truth would say yes

inconclusive!

in first instance u'd want to open the door in second not!

Asking which door leads to heaven, and choosing the opposite door, is also ineffective because: supposing person who tells the truth has the door to heaven. By asking that question he would point to his door...u would go to the opposite door!!

Answer 3

Ask either gaurd "Would the other gaurd say your door goes to heaven?"  Go thru if the answer is "no", take the other door if the answer is "yes".

By asking what the other one would say, you are sure to get exactly one truth and exactly one opposite, so you know the answer you get is the opposite of the truth.

Answer 4

Is h**l a good place? is what I would ask becaus the liar would say yes

Answer 5

You ask them what the other guard would say is the door to heaven & take the opposite door.

The honest will say the wrong door, because he knows the liar will lie.

The liar will say the wrong door because he lies.
