## Another very easy one...

My turn to twist ur brains..Answer this simple question..

You and 2 other people have numbers written on your foreheads.

- You are all told that the numbers on your foreheads are prime and that they form a triangle with a prime perimeter.
- You see 5 and 7 on the other 2 people.
- All three of you claim you do not know the number on your forehead, starting from you and now again it is your turn.
