Hello Aspirant,

If we go through the analysis of marks Vs Percentile Vs rank for JEE-Main 2020 then according to the percentile mentioned by you in the question your brother's CRL rank is expected to be in the range of 65984 - 74175 , you can check out marks Vs CRL ranks Vs Percentile from the link given below :-

Or

You can also use JEE-Main Rank Predictor to predict your rank :-

As we go through the latest cut-offs of JEE-Main 2020 of JOSAA 6th round then it shows that :-

Closing OBC rank for NIT Trichy was :-

• Computer Science Engineering branch - 2008 (Home state quota)
• Computer Science  Engineering branch - 242 (Other state quota)

And his OBC rank is expected to be around 17000-18000

So on such rank and category he has very less chances to get NIT Trichy with CSE branches even if he deserves Home state quota.

But yes if he improves his percentile in any further session of JEE-Main like around 96+ then you might have a shot at NIT Trichy.

You can check out the latest cut-offs from the link given below :-
