problem 1 states "non-negative pair". Isn't it supposed to be "non-negative pair of integers"?
What if it's just the integers? Does the bounding y still works then?

Re: Advanced P-3(BOMC-2)
It's the problem 2.4.15 from The Art And Craft of Problem Solving.
There it was said, "algebra can be used, but so can pictures."
Try solving by picture, it's much interesting and simple.

সবারই কি একই মত? বড়দেরও? আমার মনে হয় extend করলে সবার জন্যই ভালো হবে।

Re: BdMO National Higher Secondary 2007/7
Actually that is applicable when x is less than 1 but this was not given in the question, and I'm looking for a solution of this one long time so I think some of the seniors could help

What about the divisibility?
