Well, I've actually studied mathematics. Don't take this as offend, but I needed 30 seconds to solve this task. It has no such important meaning to name it with a special name. I gave this task to one of my pupils of 14 years, I'm curious to see what can she do with it.

Of course, this isn't an offend. After all, the name I gave to it was meant to be a joke. It not only sounds ridiculous but is ridiculous.
OK, let's see what one can do with this problem. After all, I am 13 so there's no point in laughing at me if I could do a simple problem."When you have nothing to say, say nothing."

Well, then accept my congratulations! It's a really nice thing that you've managed to solve that problem with your 13 years.

Oooh... a puzzle. Me like puzzles...
Well, in the strictest sense, this question is unanswerable because you left one set of variables undefined: What are the friction/cohesion properties of the balls?
OK, useless point. So then, assuming that there is no slip and the balls don't merge one into another as the ball moves from A to B, the correct answer would be ONE. Without slip, ball X rotates 600 degrees in it's travel from beginning to end, and from 600 degrees, only ONE rotation is completed. The second rotation is only 66.666... % complete. Your original question was: How many complete revolutions will the ball X make, until it reaches position b?
Oh... Somebody slap me!

Actually, Usamamuneeb... I liked this one a lot. I kid around, but I actually consider it a privilege to see someones' thought revealed in such a fashion. I hope you will grace us with more of the same in the future.
'Big ups', bro!
