Great Job ! but there is a huge difference in difficulty between 7,8 and the rest of the problems, is this your philosophy ? I mean do you think that a math contest should have problems of different levels ?

IMHO, I think that a contest must have a stable level in order that it gain a reputation. Anyway, thanks for the problems and good luck for all the participants.

By the way, can I delete my entry?Because I started doing the problems but I won't have any time this week, meaning that my final result will be like 3 points...

please suggest a book so that i can learn these things like inequalities, number theory, combinatorics etc. which are usually asked in the online Olympiads. (better if available in India) P.S. - I am in class 9, therefore corresponding level of explanation in the books, please.

Well, 3 points is better than nothing, right? It's not like you'll be fined if you do badly.
