Hello dear,

The number of students selected for jee advanced rcompletely vary year by year, like in year 2016 ,approx 20000 students were selected in jee advanced  and in year 2018 30000 students approx are selected .If the IITS fixed the percentage criteria for qualifications .Then it is hard to predict the number of students .

Hope this helps you.

Good luck.
