Question Changed . . . view it

Written on 12:29 pm by Vja Students

This is the first of a series of classic "Lady or the Tiger" puzzles. You have to choose between two rooms. Each of them contains either a lady or a tiger, but it could be that there are ladies in both rooms, or tigers in both rooms, or one could contain a lady while the other contained a tiger. There are signs on the doors of the rooms:
Room1::AT LEAST ONE OF THESE ROOMS CONTAINS A LADY .
Room2::A TIGER IS IN THE OTHER ROOM .

Solution::
The statements are either both true or both false. Which room should you pick?
If Sign II is false, then Room I contains a lady; hence at least one room contains a lady, which makes Sign I true. Therefore, it is impossible that both signs are false. This means that both signs are true (since we are given that they are either both true or both false). Therefore, a tiger is in Room I and a lady in Room II, so again you should choose Room II.

    both should be TRUE and hence it is again Room 2

    Again, a simple question. I agree with Murali, the statements are true and the room two contains the Lady. This is because, if both are false, then from sign on Room 2, there is no lion in Room 1, i.e. it contains the lady. But this contradicts the falsity of the first sign. Hence, both the signs are true and the Lady is in room two. "Here I come again, my Lady" ;)

    Both sentences are True.

    Lady Room -2
    Tiger Room - 1
