Can someone please help me with the Halloween Candy code coach?

Question

https://code.sololearn.com/ckHakpRdxVGZ/?ref=app

I just don't understand why doesn't my code pass the 3 hidden tests.

Answer 1

int a= (int)Math.ceil(200/(double)houses);

Answer 2

I just finished this one myself in C# and my problem was I needed to round the numbers UP, not just round them in either direction.

Answer 3

Thanks to all of you!
