Here’s the link of the question paper. I need the explanation for the solution of Question #1.
I am taking participation in ZIO for the first time and I have no clue for solving the ZIO previous year question paper. So please suggest me some topics related to mathematics and Programming which I must know to solve these questions.
Please help me out!

Hey,
In ZIO you don’t need any mathematics or programming. Mathematics uptil class 8 or 9 are enough for ZIO. Neither do you need any idea of programming.
There are 2 ways which I do these ZIO problems:
- Think of a logic, and logically find out the answer.
- Do it manually (takes me an hour to solve one question)
So its better to think of a logic and find out the answer.
You should start with 2002, it has explanations along with the answers. The others is just about practice.
For the first question, I can give you in the form of hints:
Hint 1
The logic is related to Lowest Common Multiple.
Hint 2
Take any number of integers whose sum is n. Note, the number of integers can be greater than 2 too.
Hint 3
The answer will be L.C.M of the numbers. Thus, to maximize the answer, you maximize the L.C.M.

Thanks for the hints, I was able to solve it with those hints you gave. But when I start solving ZIO questions it feels to me that I am taking too much time to crack the logic for a single question (approximately 50 min ) and sometimes I can’t even crack a logic. Please tell me how should I improve myself.

Learn combinatorics and sometimes manual DP also helps in ZIO problems

Can you please suggest a resource to understand these two topics as an absolute beginner?

Thanks for these two links they seem to cover everything I need to know but for the combinatorics as I said I am a beginner I need to know some basic knowledge about it before practicing the questions related to it.
