Answer:

According to the question, there is no solution. If we add three odd numbers, it will always produce an odd number.

Step-by-step explanation:

Just using the numbers given here, it's not possible, because we know that, odd + odd = even.

even + odd = odd.

30 is an even number, the answer of 3 odd numbers must be odd, it's a contradiction.

It will possible when if we add factorial function with the number 3 then it will produce even number.

11 + 3! + 13 = 30
