Hi Priyanka.
It is difficult to give an exact answer for this question as the exam you're talking about is JEE Advanced. It is conducted by different IITs every year, this year being IIT kanpur. So, we can't expect anything. the pattern may be different, the difficulty level may be different. So, as a rough answer, I can just say that youy'll have a rank around 30k or 31k if you score about 30% in JEE Advanced.
Good Luck.
