Hello aspirant,

I hope you are doing well and good. As you mentioned that you have scored 48 percentile in JEE mains exam. As you asking for the college to get admission at rank is very tough because your percentile is too less so you have no chance of getting admission in any government college because last year the cut-off for the OBC category is 75+ percentile. So don't lose hope you can opt any private colleges for the BTech course.

Goodluck!
