#15 - Samsung Logic Interview Puzzle

A lion and its tamer are standing inside a cage that measures 1 unit in radius. Both of them can effortlessly run at the speed of 1 unit maximum.

1) Suppose the lion is hungry, will he be able to eat up the tamer?
2) If yes, how long can the tamer survive?

View Answer Discuss

There can be two possibilities:

The tamer runs on the perimeter
If he runs on the perimeter, the lion will eventually catch him. If the lion follows the radius of the tamer, his trajectory will be half the circle and not a spiral. Thus he will catch the tamer in a finite time.

The tamer does not runs on the perimeter
If he does that, clearly he has an escape strategy and that will work for an infinite time.

The killer did not need to be present at the crime scene. He used sort of an artistic technique to kill the victim. The incision was made by the very fine and this incision blade which is barely visible to naked eyes. It was stuck in victim's belt at any random point of time and he did not feel much due to the extremely fine surface of the blade. When the man undressed, he had to remove his pants due to which the incision blade was removed from his body cutting finely in its way out.
In this manner, the victim dies with the extreme blood loss and there was no evidence left.
