Dear Saumya, 

MBBS is a profession where you can earn a huge amount of money after becoming a doctor but before that you also have to spent a huge amount of money if you want to study in a private college.So ,generally the annual fees of a private medical college ranges from 8 lakh to 11 lakh per year, also more in some cases. But few colleges which offer MBBS course in a lower amount are:
1. Terna Medical College and Hospital,Maharasthra(4.82 lakh per annum)
2. Annasaheb Chudaman Patil Memorial College(4.15 lakh per annum)
And also some other colleges with more or less same fee- Institute of Medical science and Research,SMBT institute of medical science and Research and SRM medical college where annual fees ranges from 95k to 1 lakh and any colleges under COMED k in karnataka will offer you mbbs course only in 4.65 lakh per annum which is less compared to other private colleges. Hope this helps. Good luck!
