Question

In 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29.In this numbers addition of three numbers is 30.(?+?+?=30)

Answer 1

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's not possible .

but when we use factorial concept , it will be possible. How's it possible ? Let see
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!

Answer 2

The addition of three numbers is 30 not taken by this series.

This is because of series comes up with the odd numbers.

But the number 30 is even number.

No one can get the addition of three numbers in the series.

Make use of the factorial method is the great way to get the answer.
