The sum of three odd numbers gives an odd number
So, the sum of 3 given odd numbers doesn’t 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 can’t use it.
If there will be an allowance of factorials, then the answers will be
3! + 15 + 9 =30

3! + 11 + 13 = 30

⇒Let me first say you that , when we add odd numbers  ,we do not get a result of even number .

To do this sum , We can solve only through Factorial method ;-

15 + 9 + 3 ! = 30

Here , 3 ! will be equal to -  1 ×2 ×3  .

- Therefore , The answer is - 15 + 9 + 3 ! = 30
