Hi

This difficult to predict the marks/percentile / rank you require in JEE mains to get into NITs etc as closing rank keeps changing every year  depending upon various factors like

----------) number of students/ candidates  that appeared in the  jee main exam,

-----------) number of available seats,

-----------) jee main examination difficulty level.

-----------) branch preference by different candidates

-----------) the category you belong etc.

But yes,

When we go through previous year trend then ,

Under other state quota , closing rank for some of the nits for which closing rank goes low are listed below along with their closing rank in the 6th round of josaa counselling 2021 for sc category  :-

------------------) National Institute of Technology, Andhra Pradesh :- Metallurgical and Materials Engineering :- 9135 sc rank

------------------) NIT, Raipur :- Bio Medical Engineering :- 9446 sc rank

------------------) National Institute of Technology Agartala :- Physics (5 Years, Bachelor of Science and Master of Science (Dual Degree)):- 10530 sc rank

You can check the same at its official website for which link is given below:-

So, to get a seat in NITs, you need at least around 9k -10k sc rank, and for that you need at least around 85 percentile as per past year trends

So, with 49 percentile your chances for NITs is extremely low.
