Hello Seshadri sn..we can't predict marks as it is percentile, but we can predict the rank.

According to careers360 rank formula, 

Rank formula= [(100-total score) * (no of students wrote exam)] /100

No of students attended are 874469.

So your expected rank will be nearly around 34,629.

As per previous year jee mains, any rank below 2,00,000 will be qualified for jee advanced.

So according to expected rank of yours, you are eligible for jee advanced.

Hope this helps you. All the best.
