Hello Rahul Nitish..

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 6,51,927.

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 may or may not be eligible for jee advanced as we can't predict category rank.

So don't worry prepare well and write april jee mains well. best of the two exams will be considered.

Hope this helps you. All the best
