I think in addition of 400 mbbs seats it might be 420 plus

Hello dear student , first of all there is no different cut off for girls and boys differently there's always cutoff marks for the category . For unreserved category the expected cut off is 701-134 marks. Although by just clearing and obtaining the lower marks you might not able to grab a seat in government medical college plus when you belong to unreserved category the competition is heigher. Here i am attaching a link for further knowledge
