In The Search Of Spirit.....

You are an expert on paranormal activity and have been hired to locate a spirit haunting an old resort hotel. Strong signs indicate that the spirit lies behind one of four doors. The inscriptions on each door read as follows:

Door A: It's behind B or C.

Door B: It's behind A or D.

Door C: It's in here.

Door D: It's not in here.

Your psychic powers have told you three of the inscriptions are false, and one is true. Behind which door will you find the spirit?

Psychic Expert Needs Logical Thinking

Clues that psychic expert can use!

Let's believe our psychic powers & remember only 1 inscription can be TRUE & other 3 must be FALSE.

1. If the spirit is really behind the Door A , then both the inscriptions - on Door B & Door D are TRUE.

.

2. If the spirit is behind the Door B then again 2 inscriptions - one on Door A & Door D are TRUE.

3. If we assume the spirit is behind the Door C then both the inscriptions that are on Door C & Door D are  TRUE.

.

4. So we are only left with the Door D & that's where wanted spirit lies. In this case only inscription on Door B is TRUE & rest of all are FALSE.

And let's not forget to congratulate an expert within us for this wonderful achievement!
