**The sum of three odd numbers gives an odd number**

**So, the sum of 3 given odd numbers doesn’t 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 can’t use it.**

**If there will be an allowance of factorials, then the answers will be**

**3! + 15 + 9 =30**

**3! + 11 + 13 = 30**
