Hello Joshik Roshan

                       Hope you are doing well.First of all I congratulate you on clearing jee mains.Based on the previous year's comparison i.e 2018 for General candidate if gets 155 marks then his rank is between 5400-5500.This might have brought you some clear idea to you.And in addition to that when you compare past 3-4 years marks the ranks gets changing.

Hope this helps you.

All the best. 

Hey bro, it totally depends on the cutoff. One can't say about the ranking, as cutoff can be change drastically over a year. 

You should wait for the results as no one can tell the exact rank with the marks as different year has difediffe cutoffs. But if you want an idea, than you can get around 90,000 rank
