Hardest maths question ever

[Black_Apalachi]

I bet I can make up an impossible, nonsensical maths question that is equally as hard

can someone tell me how you get 15 for the second question?

You guess and come up with a random answer. Seriously.

Assuming the answer to i is 24 rather than a lower multiple of 8, there are 21 kids with boots and 18 with footballs. There is *** all way of finding out from that how many own both because while it's likely that people owning the balls will also have boots there's still plenty of possibility that that's not the case - the answer can be 18 at most but also could potentially be 15 (as per the given answer in the spoiler) or anywhere in between.
