Re: A simple Puzzle
second day itself...y bcoz if he enters the first day he'll spent 1 day and come out of that..and then the remaining 2 doors get shuffled(y b'coz he knows very well from which door he came out) and he will enters the 2nd one(which is in real the thrid one..the heaven)...
is that correct |

I have presumed few things in the first place. One of them is that he enters one door and that door remains in its place till he comes out. I mean that that door cannot get shuffled. He cannot enter into 1st door and come out from 2nd door. Secondly I have presumed that the doors get shuffled only after he has entered into any. So the doors get shuffled only once. It is not mentioned that the doors get shuffled each day. So suppose he entered 1st door. He finds it hell. He will be living there for say 1 day. Then next day he will come out the same door and now he knows that the doors have been shuffled yesterday after he has entered into the door. He can enter into 2nd or 3rd. He now knows that yesterday's 2nd door is today's 3rd door and vice versa. Let us say he enters 2nd door which was earlier 3rd door. There if he finds hell again and living there for 2 days. Now when he will come out 2 days later he knows that the doors have been shuffled 2 days ago when he entered. So what was 1st door is now 3rd door and vice versa. So he can safely enters 1st door and get into Heaven. Please let me know if there is any error in my thinking. |
