Hello pratika

Well, it's very difficult as of now,to predict the cutoff for JEE mains based on percentile.You can first calculate your rank by rank=(100-percentile)*874469/100.With this rank,you can compare previous year's cutoff for different colleges and can predict some of the colleges you may be getting.But remember this is not the final rank.It will change based on the april session of mains.For more details viisit https://engineering.careers360.com/jee-main-rank-predictor  Hope this helps.

Good Luck!
