Question

1,3,5,7,9,11,13,15 _____+____+_____=30

Answer 1

9 + 7 + 15 = 30..

........

Answer 2

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
