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.
Room 1 :False
Room 2 :False
Room 3 :True
Room1 - Lady
Room2 - Tiger
Room3 - Tiger
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
