Question

adding 5 odd numbers =30 fill the boxes using (1,3,5,7,9,11,13,15)u can also repear the numbers

Answer 1

We will not get the result = 30, because by adding odd numbers 5 times the result should be odd. Here, the result is 30 which is an even number, and hence it is not possible, whether we repeat the number also.

Answer 2

3!+1+3+13+7=30
Hope i helped u:)
