Hii

You can only calculate the approx rank as of now but not the accurate rank because the final results are yet to be declared. Here is a formula to calculate the approx rank
100- your score * 874469 /100
so the approx rank would be 10231.

But remember for the final ranks you need to wait for th official rank list which will be released only after the final results in april

Thanks!!

Since JEE Main is going to be conducted twice in this year in various shifts on various days the exact rank cannot be said. The approximate rank for percentile 98.83 will be around 10231(+-). 

Note that after JEE Main is again conducted in April the rank has probability to change. 

If have any other queries do mention it down in the comment section.
