I believe youre referring to 140/300 in JEE Main. You percentile will be approximately between 96.9-97.3 with this score and corresponding JEE Main Rank anywhere around 30k and a OBC NCL Rank anywhere around 7-7.2k.

The last Cutoff for OBC NCL Delhi Region at DTU Information Technology, last year was CRL 67k. Hence, you have fair chances of securing IT, since youre a Delhi Region Candidate besides having OBC Categorical Advantage. Perhaps till last round of JAC Delhi Counselling you even have chances of Computer Engineering at DTU.
