as it is not possible to get an odd number by adding odd no.s odd no.of times, we could do it by using factorials,for example:
11+13+3! -=30
[ by this way,you may also find other combinations ]
11+13+3! -=30
[ by this way,you may also find other combinations ]

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
