Sixteen Horse Race
There was a 16 horse race in progress at the race course but I missed the finish. I asked 6 of my friends to tell me the number of the winner. These were their answers:
It was an even number.
It was an odd number.
It was a prime number.
It was a square number.
The number had 2 digits.
The number was between 6 and 12.
Only 4 of my friends told the truth. Which number was the winner?

di anyone find it hard?
no, pretty easy, but good logic.
They say odd.
They say even.
One is a liar. (no number is odd and even)
They say prime.
They say square.
One of them is lying. (1 is not a prime number, because its only factors are 1. A prime number has 2 factors. Have you ever seen a prime square?)
So it must have 2 digits and must be between 6 and 12. So it is either 10 or 11. 10 isn't prime or square so it can't be it. So it must be 11.
