Hello aspirant,
We can't exactly tell the percentile for you to get into any IIt's because every year it is different. Let me explain you about how the percentile or rank is effected every year in different aspects. Your percentile gets effected by the toughness of the paper, number of people attempting the exam, previous years cutoffs.
As per last year for an OBC category student the minimum percentile should be 9% in each subject and 31.5% in aggregate .As you didn't mention weather you are an OBC-NCL category or OBC-CL student, If you are an OBC-CL student you wont come under the reservation.
I will be providing you the previous years percentile cutoffs and rank cutoffs of jee advanced you can further check over there.
