The court takes decision to relax the sentence given to criminal if he can solve a puzzle. Criminal has to take decision to open one of the doors.
Behind each door is either a lady or a tiger. They may be both tigers, both ladies or one of each.
If the criminal opens a door to find a lady he will marry her and if he opens a door to find a tiger he will be eaten alive. Of course, the criminal would prefer to be married than eaten alive.
Each of the doors has a statement written on it.
The statement on door one says, “In this room there is a lady, and in the other room there is a tiger.”
The statement on door two says,”In one of these rooms there is a lady, and in one of these rooms there is a tiger.”
The criminal is informed that one of the statements is true and one is false. Which door should the criminal open?
The criminal should open door number 2.
If the 1st statement is true, then the 2nd statement will also be true.
So we can conclude that the 2nd statement is true and the 1st statement is false. From the 2nd statement, we know that there is a lady in one of the rooms and a tiger is in the other room. The lady has to be behind door 2 as the first statement is not true.
