Hi Guys, I just want to say that JOMO 5 has started! Please reshare and tell your friends about it. You can check out the paper here. Please read the rules before starting

I've told all of my friends! This is going to be really fun but @Yan Yau Cheng could you go a little easy on the trig? After all, this is Junior. I just finished. :D

What ? I think the correct file(ques 2 problem fixed) is now uploaded on the website ..... All participants , we're sorry for that inconvenience , really!!

@Bogdan Simeonov@Sharky Kesa
After Triple-checking, there IS a problem in question 2, we are terribly sorry and we have edited the question.
@Finn Hulse You might want to resubmit for question 2 as well since you already submitted

We are sorry Bogdan and all others for the inconvenience but there IS a problem in question 2 ....
We have edited the file and soon , the correct version will be uploaded on the website ..... Apologies for your time that it consumed unnecessarily .....

I am a problem writer at JOMO but i also feel that this one is easier than previous JOMO (of course feeling easy/difficult may differ among people) .... Go on , all the best ! Progress expected this time .......

I didnt attempt any of the contest. If u are saying of the previous combinatorics contest, then I admit my worst prepared topic is combinatorics, while my strongest topic is inequalities.. But, previous contest was also easy, but I didn't get a few. As for this contest, I got all ques but one till now.. R u taking in it? all the best then

Arrgghh... I cant do this, the problems arent bad but it just takes too much to convert everything to PDF 's and everything, i barely have that much time. sorry!

The proof problems were a bit strange. No casework, no induction, not really much of anything! :P

Really? Last weeks for me was the easiest, this one for me was moderately tough.

For question 2, I can't find any non-negative integer solutions for \(x\), \(y\) and \(z\). Did yours have any negative numbers?
