A dead body is found at the bottom of a multistory building. Seeing the position of the body, it is evident that the person jumped from one of the floors, committing suicide.
A homicide detective is called to look after the case. He goes to the first floor and walks into the room facing the direction in which the body was found.
He opens the window in that direction and flips a coin towards the floor. Then he goes to the second floor and repeats the process. He keeps on doing this until he reaches the last floor. Then, when he climbs down he tells the team that it is a murder, not suicide.
How did he come to know that it was a murder?
You have 3 boxes. One of them contains a prize. You were allowed to pick just one of them.
You pick - and it's empty.
With 2 boxes left, you now have one box in your hand and another box in front of you. If given the chance to exchange your box with the box in front of you, would you do it? Why, and why not?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
In the beginning, with 3 boxes, things were simple. You had a chance of 1 in 3 to find the prize. NOW we know that one of the boxes is empty but you still made a guess of 1 in 3, now you have a new choice of 1 in 2. Your probability goes up and that is why you SHOULD CHANGE THE BOX.
Don't feel bad if you disagree, this riddle has been hotly debated.

One evening there was a murder in a house where there lived a married couple with their 2 children - their son and daughter. One of these four people murdered one of the others.
One of the members of the family witnessed the crime.
The other one helped the murderer.
These are the things we know for sure:
1. The witness and the one who helped the murderer were not of the same gender.
2. The oldest person and the witness were not of the same gender.
3. The youngest person and the victim were not of the same gender.
4. The one who helped the murderer was older than the victim.
5. The father was the oldest member of the family.
6. The murderer was not the youngest member of the family.
Who was the murderer?
The mother was the murderer.
We know from fact number three that the youngest person wasn't the victim, and from the fourth fact we know the youngest person wasn't the helper and from fact number six the youngest person was not the killer either. Therefore, the youngest person can only have been the witness. If we make up a chart there are now three possible combinations:
Oldest person (father) H H M
Next to oldest (mother) V M H
Next to youngest (son) M V V
Youngest (daughter) W W W
(H = Helper ; V = Victim ; M = Murderer ; W = Witness)
We can work out from fact number five that the father was the oldest and from fact two that the youngest person must have been the daughter. Therefore the next to the youngest must have been the son and the next to the oldest, the mother!
