Hello rajan .As you are enquiring about jee mains let me first clear you that it all india level so its cutoff is not fixed it varies from year to year depends on the colleges tthat takes admission through jee mains and the number of seats they carry example if only one college accept through jee mains so the number of seats in that will be the cutoff winner . But as seats increases cutoff decreases so generally 2lac 24000 students qulaify jee mains now a days cutoff is getting low bcoz of examtoughness so if u r general candidate and you score more than 90 for sure you will qualify jee mains .

Hope it helps
