in mathematics, it is impossible to get an even number by adding three odd numbers.
here, 1 , 3 , 5 , 7, 9, 11, 13, 17, 19, 23, 25, 27, 29 all are odd numbers.
so, it can't possible .
but when we use factorial concept , it will be possible. let's take
first number is 9
second number is 15
and 3rd number is 3 !
then, 9 + 15 + 3! = 30
because we know, 3! = 3 × 2 × 1 = 6
hence, we have to choose 9, 15 and 3!
[note :- there are so many possibilities , of we take factorial concept . so don't be confuse]
