I'm horribly bad at maths, and I am sure I am missing something obvious here, but can't figure out what.

Let's say that a bowl can contain 20 apples. What would be the number of the bowl where the 194th apple resides?

It'd be bowl number 20. That's assuming that the other bowls are full to capacity....

Yes, all bowls are at full capacity. How'd you reach the number?

Actually, I just did (20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20), and it seems the 194th apple would be in the 10th bowl. However, I have no idea how else to reach this number.

Actually, you're absolutely right. I should refrain from posting when I've just finished a bottle of wine! :)

I did it as 20 x 9 = 180, therefore apples 181 to 200 are in the 10th bowl.

Divide 194 by 20 and you get 9.7. But remember there are more than 9 full bowls, so the 194th apple would indeed be in the 10th bowl.

Yes, indeed. If the answer is greater than x.0, then the answer is integer x.0 +1.

I also divided 194 by 20, and got 9.7 (round to 10)----and, as the other poster said, the tenth bowl would NOT contain 20 apples; because, if it DID, you would have 200 apples.

Label 10 bowls as #1, #2, #3, ..., #10

Put apple #194 into the bowl #1. Choose 19 apples at random and put into bowl #1. Choose 20 apples at random and put into bowl #2. Repeat for bowl #3 and up to bowl #10.

Then apple #194 is in bowl #1.

Well yeah, sadly, I can't trick a computer into believing that, at least not for the retrieval of information.
