Hello Alok, 

As per the previous year cutoff trends, and considering you are from the All India Unreserved category, the opening and closing score for MNLU Nagpur was 108 and 90 respectively. The opening and closing rank cutoffs were 1200 to 4000 respectively. 

While for MNLU Mumbai, the opening and closing score was 116.25 and 110.5 respectively while the ranks ranged from 575 to 1050. 

It seems as if you have a very good chance in MNLU Nagpur as your score and rank both fit the cutoff trends, and even if the cutoffs are supposed to be higher this year, you really seem to have a good chance. 

As for MNLU Mumbai, your score fits the range but your rank doesn't. So, I would say you have 50-50 chances of getting admission here. Wait for the rounds and let's see what happens. Till then, consider other NLUs as well.

All the Best!
