Hello,
For admission to DTU and NSUT, candidates need at least 60% in PCM (Physics, Chemistry, Math) in 12th. However, JEE Main requires 75% in boards or top 20 percentile for eligibility. Since DTU and NSUT admissions are through JEE Main, the 75% rule applies . So, yes, they follow the 75% criteria indirectly due to JEE Main requirements.
Hope it helps !
