Hello Anurag. I would like to tell you that the final results have not been declared yet by the NTA. The result will be revised after the second attempt of JEE Mains Paper 2. You need to wait for the final results to know the exact cutoff. However for your reference I am sharing a link with you which consists of previous years NITs cutoffs.
