What Question Should You Ask?
Puzzles are not always about answering a question. Sometimes it is also about asking a question. Try asking the right question to solve this problem.
You are in a room with 2 doors. Behind 1 door is a coffer overflowing with jewels and gold, along with an exit. Behind the other door is an huge, hungry lion that will pounce on anyone opening the door. You have no clue which door leads to the treasure and exit, and which door leads to the lion.
In the room there are 2 more individuals. The first is a Sachcha, who always tells the truth, and the second is a Jhoota, who always lies. Both of these individuals know what is behind each door. You do not know which individual is the Sachcha, or which one is the Jhoota. You may ask one of the individuals exactly 1 question. What should you ask in order to be certain that you will open the door with the coffer behind it, instead of the hungry lion?

Like you I am a fan of vedic maths and as such I am surprised it isn’t taught in schools (in the UK) and an trying to raise awareness of it here. Anyway to your question, it does come down to maths in a way. If we assign a value of +1 to a truthful person and a value of -1 to a liar and then if we times them together,
1 x -1 = -1.
Therefore the question to ask would be along the lines of “Which door would the other individual advise me to go through to get to the riches?”
Then we would take the other door (the one not indicated) as being the ‘positive’ or correct door for the riches.

Well, I will question any one of them, “If I ask the other person, what is the way to the coffer, which door will be show?”. And i will go to the door which was not pointed by him! Whoever it is, sachcha or joota doesn’t matter!i will get to kow the door to the coffer!!
July 1st, 2012 - 11:43
i will not ask any one directlly i will go to open any one of the door as the two persons sacha an joota knows the answer if the door behind is lion means it will not only eats me even them so sacha will say truth and joota will be silent
May 1st, 2012 - 13:36
I’ll ask “what will be the answer given by ur brother for which door contains treasure?”.If he is the sachacha, then he might tell 2nd door then i choose 1st one why bec’z the other will tell always lie and the same rule applies for vice-versa.
April 30th, 2012 - 16:17
i just screem “” joota” ,point out the room with jewls’. as he shows the wrong one normally i will opt for the other Meanwhile the sachhaa who never lies, keeps queit as i screemed joota

Well I tell both of them first , my name first “abc”. And then will ask anyone whether my name is “abc” . The nalayak one will tell lie so I’ll know other guy will tell me truth about door vice versa
The true question is, If there are two doors and then how did the guy came inside the room

I would ask one of the person:- “If I ask the other man if the door behind him had the coffer, what would be his reply?”
If the that man answers “The other man would say yes”, I will go through the door of person whom I had asked question. If he answers “the other man would say no”, I will go through the door of the other person.

I will ask one of the person – “If i ask the other guy which door leads to the coffer?”. Since i dont know which is Sachcha or Jhootha, this question will make sure it doesnt matter to whom i ask. So if its sachcha to whom i asked, he ll reply that the other guy would have told door no 2 (lion) and hence i should automatically select door no 1 (coffer). If it was Jhootha to whom i asked, he ll reply door no 2 again since sachcha would have told me door no 1 and since this guy is jhootha he has to lie to me. So automatically i would again choose the door no 1. Thus in any case, i ll ask this question and select the door different from that given as answer.
