David has 90 Ballons ( 3* of Rohan)
& Rohan has 30 Ballons

D gives 10 i.e 90-10 = 80 Ballons
R has 30+10 = 40 Ballons ( Twice as of Rohan)

D gives 80-20 = 60 Ballons
R has 40+20 = 60 Ballons

So Equal

Rohan havew 20 while david have 60 balloons.

One day at the Rohan's house, Rohan and Pawan were playing a game. The rules of the game were simple. You try to make the other person flinch without touching them. You have five seconds to do this. If you do this in five seconds, you earn a point. Instead of using points, Rohan and Pawan used pieces of popcorn. After a certain amount of time, Rohan had seventeen pieces, while Pawan only had eleven. After more time, Rohan doubled his amount, while Pawan tripled his amount! After even more time, Rohan gained seven pieces, while Pawan gained only four.
