in university hostel: room rent is 100 pm and mess charge depends on the amount that u eat but generally it would be around 1750...
in private hostels: room rent ranges from 750 to 2000+ and only some private hostel provide mess,so u need to eat from outside..but don't worry there are lot of hotels providing north indian and south indian food.....so if u are staying outside nearly expect around Rs 5000pm
