The sum of three odd numbers gives an odd number
So, the sum of 3 given odd numbers doesnt results 30
So, it is an impossible factor
here we can't use 3! too
because 3! [3×2×1] results a even number 6
so we cant use it.
If there will be an allowance of factorials, then the answers will be
3! + 15 + 9 =30

3! + 11 + 13 = 30
1 5 1

When adding odd numbers we do not get a result of even number

⇒ So this sum is only possible through Factorial method

so the answer is -

                       ⇒ 3 ! + 15 + 9 = 30
1 5 1
