Sometimes i find a high rating question very easy like G1 (https://codeforces.me/contest/1840/problem/G1) of round 878 div 3 but its rating is 2200. sometimes a low rating question like (https://codeforces.me/problemset/problem/1773/F) takes too much time . how they decide rating of question , on their own perspective or number of participate solve that question in contest. their question rating system is too much confusing.

It depends on rating of people who solved it and their number. I don't know the exact formula, but it's based on the fact the x-rated people have 50% chance of solving a x-rated problem. That's why you might find an easy 2200 rated div3g1. Not many people get to it so it gets higher rating
