You need focus and attention here to solve this puzzle. By that I mean there is no equation here. It's a tricky one but I'm assuming you people should easily get it.

I think I got it:


You have to turn upside down the ball 9.


Thanks for the reward.
I spent 2 minutes to see if there is any possibility but in a simple way, it cant be 30.
It will be 6+11+13 and for 6 a ball showing 9 should be turned upside down for 6. Hope I am right.

As the others have said, you'd need to invert the yellow 9 ball but in reality, the yellow nine ball looks like this so that doesn't make much sense!

For the sake of entry though.... 6,11 and 13 make 30!



The only possibility is to invert number 9 to make 6 but don’t know if it’s permissible and then 6+11+13=30
