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

no we can't get 30 by adding 3 odd numbers.
because get odd number by adding one even and one odd.
for 3 numbers we have to add 2even numbers and one odd number.
but in this question it is not aplicable.Therefore it impossible.
