You need 75% in 10+2 (general category).

I don't think that you are eligible for NIT Rkl. Try for some other Universities.
All the best.

No way there is no chance it is time work hard.

Your expected JEE Main AIR is about 63649. You have not write about the category you belongs. However keeping the last year of trends in consideration and if you are from general category with Odisha home state, than you can get the following engineering branches.
1. Food Process Engineering
Further if interested in Integrated M.Sc. than you can get the Integrated M.Sc. Chemistry.
