Solution:

Complete Question is in attached picture

Given balls have numbers

1    3     5    7

9   11     13   15

We have to add three  balls to get 30

in 1st go it looks impossible to get 30 as sum

as sum of  3 odd numbers will be odd

then just seeing carefully these are balls

and we can rotate ball by 180°

then ball 9 will be come ball 6

Then 6  + 11 + 13    = 30

So three balls can be used 9  , 11 & 13

Ball  9 has to be rotated about 180°
