Hi Hardik

The minimum marks required for admission is defined as the cutoff. This implies that if you score less than the cutoff, you will not be entitled with admission. So, I am sharing the cutoff of NIT Delhi with you through the table given below.

This cutoff is of 2017, you can use this to estimate the cutoff for 2018.
