Answer 1

We wont get a even number if we add odd numbers an odd number of times.
So this has to be solved using factorial-
3! + 11 + 13 = 30.This will be a solution.       

Answer 2

Odd numbers don't add up to give you an even number.
It is possible only in case of factorial.

3!+1+3+13+7=30 

3!+3!+3!+3!+3!=30
