Hi Ratan,

Based on the above information provided by you, your probable JEE Main rank will be approximately 25,641-29641 and your probable category rank will be 510-810, considering the total number of students appearing for April Jee Main to be 1152650. Based on the category rank, your brother can easily get admision in core branch in NIT Tiruchirappalli. Below I will attach a link that shows the closing rank of previous years for different branch:

Hopefully this helps.  

Hello Ratan. Thanks for connecting with Careers360. Yes definitely, with this score your brother holds great chances of gritting a seat at NIT trichy. But this is just a prediction, the final cutoff will be declared by NTA only after the April session of JEE MAINS. But your brother need not worry as with this percentile, he is eligible for almost all the top colleges in India. Good luck.
