Answer 1

"We cannot use direct sum to get 30 because it is even number and the series contains odd numbers.

We can only use factorial method to get the answer as 30.

3! + 11 + 13 = 30

3!+9+15= 30

3!+3!+3!+3!+3!= 30

11+1+3!+3!+3!= 30

5+7+3!+3!+3!= 30

11+7+3!+3!+3!= 30

3+5+7+9+3!= 30

1+5+7+11+3!=30

1+1+3!+11+13=30

1+3+5+3!+15=30 and many more.
