Question

_+_+_=30
Fill the box using (1, 3, 5, 7, 9, 11, 13, 15)

Answer 1

it can be done by using factorial 3!+9+15

Answer 2

no, it is an impossible event
because the sum of three odd number gives an odd number only, but here it is given that the result will be an even number so it is not possible
and we dont have to use 3! too here
because 3! results an even number i.e., 6
