Hello Omkar

It's really difficult to predict the jee mains qualifying cut off to be eligible for jee advance as it keeps changing every year depending upon various factors like number of students that appeared in the exam, kind of marks scored by students, toughness level of exam, highest marks obtained  etc  but with 80.41 percentile you have good chances to be eligible for jee advance.
So, yes you may clear the jee mains cut off for obc category with 80.41 percentile to be eligible for jee advance

For example, last year 74.3166557 percentile was the cutoff for Other Backward Classes (OBC-NCL) to be eligible for jee advance

I hope that it helps you

Thankyou
