Question

what is ___+___+___=30 (1,3,5,7,9..)

Answer 1

Sum of three odd numbers can never be equal to even number.

So, we can not solve this question directly but we can solve it using factorial, etc

We need to use odd numbers - 1,3,5,7,9,11,13,15,...

So, we can solve like this,
3! + 11 + 13 = 30

Verification :
= 3! + 11 + 13
= 6 + 11 + 13
= 30

Hence solution is 3! + 11 + 13 = 30
