புதிர்...

இது கொஞ்சம் tricky யான puzzle தான். முடிந்தால் முயன்று பாருங்களேன்...

Which one is the door to the Heaven?
One guy died and was sent to the god to select his destiny. The god gave him a chance to choose one out of Heaven and Hell. God’s directions are as follows.

“Turn from here and go straight. There will be two doors. One of them is to the Hell and the other is to Heaven. Which leads to where, that you will have to find out by yourself. And there will be two guards kept for the security. One of them is a liar and the other one always tells the truth. Who lies and who does not is for you to find out. You can ask only one question. If you want you can ask from both of the guards, but must be the same question. Once you select the entrance, there is no way back. So be vigilant.”

So the guy went to see the guards, and asked a question and of course found the entrance to Heaven.

What can be the question he asked from the guards?

it is enough if he asks only one of the guards. any one of them will answer/show the door which shall actually be the door for the hell. the other door should be chosen as the entrance for the heaven.

I think you both are wrong.

The person would have asked only one of the guard and found the door that leads to heaven...And the question would be...

" Is the liar guarding the door that leads to heaven?"

- If the answer is 'Yes'
He should open the other door and reach heaven

if the answer is No
He should open the same door that leads to heaven

Let me explain this,

Let us say the answer is 'Yes' and he is the liar

then obviously he is lying which means the other door leads to heaven.

Now Let us say the answer is 'Yes' and he speaks truth,

which means again he is not guarding the door that leads to heaven :)

You can apply the similar logic if the response is NO
