Hello Aspirant,
Since the new pattern was adopted by National Testing Agency for declaration of result of JEE-Main, it is little bit difficult to predict your category rank from NTA score or percentile. Although your general rank can be calculated using the general formula as given below :-
(100 - your percentile)*869010/100
According to this formula your rank would be near about 43,000. For category rank you have to wait for the final results to be out.
You can also predict your college based on your percentile and category using the JEE-Main College Predictor Tool. Link for the same is given below :-

I hope this information helps you.
Good Luck!!
