Hello Aspirant,
See it is quite difficult to tell you an exact figure of your CRL rank because it keeps on changing every year depending upon various factors but yes we can help you with approximate figures on the basis of analysis of previous year's data.
So If we go through the analysis of Percentile Vs CRL rank for JEE-Main 2021 then according to the percentile mentioned by you in the question your CRL rank is expected to be in the range of 299514 - 336697 .
Note that the ranks which are predicted are only the expected ranks on the basis of previous year's data so your actual ranks might vary depending upon current factors.
Based on such rank you have almost no chances for ME neither in NSUT nor in DTU because the closing CRL in final round was around 2 Lakhs for NSUT and for DTU it was around 1.8 Lakhs for ME branch in 2021 for OBC category.
So you need to improve your score, at least take it around 87+.
