Helo Aspirant,

According to the percentile you have mentioned in the question your approximate rank would be near about 9,999 or 10,000 and this rank is calculated  using the formula

(100-your percentile) *869010/100

Here 869010 is the number of candidates appeared for JEE-Main January Session. But if we go for category rank then it is little bit difficult to predict because it directly depends upon the number of students appeared with the same category as of yours and also the other category students along with some other factors.

However I would recommend you to use JEE-Main College Predictor to predict your college according to your percentile and category :-

I hope this information helps you.

Good Luck!!
