Again lady & tiger

Written on 1:43 pm by Vja Students

There are now three rooms to choose from. Only one contains a lady while the other two contain tigers. The signs on the doors of the three rooms are as follows:

Room1:A TIGER IS IN THIS ROOM
Room2:A LADY IS IN THIS ROOM
Room3:A TIGER IS IN ROOM II

At most one of the three signs is true. Which room contains the lady?

Solution::
Signs II and III contradict each other, so at least one of them is true. Since at most one of the three signs is true, then the first one must be false, so the lady is in Room I.

    Room 1: Lady
    Room 2: Tiger
    Room 3: Tiger

    Statement on room 3 is correct.

    ROOM1 (TRUE) - TIGER
    ROOM2 (FALSE) - TIGER
    ROOM3 (FALSE) - LADY -> But the sign contradicts. So this scenario is ruled out

    ROOM1 (FALSE) - LADY
    ROOM2 (TRUE) - LADY -> But the sign contradicts. So this scenario is ruled out
    ROOM3 (FALSE)


    ROOM1 (FALSE) - LADY
    ROOM2 (FALSE) - TIGER
    ROOM3 (TRUE) - TIGER
    -> This is a valid scenario. So the LADY is in ROOM1
