Do u mean Management quota??

No not management quota but private colleges like:
Viswabharathi Medical College, Kurnool
Fakhruddin Ali Ahmed Medical College, Barpeta, Assam
Katihar Medical College, Katihar
Lord Buddha Koshi Medical College and Hospital, Saharsa
Mata Gujri Memorial Medical College, Kishanganj Narayan Medical College & Hospital, Sasaram Chandulal Chandrakar Memorial Medical College, Durg

Hope this helps.

but I have seen people in Karnataka last year to get seats in management quota with scores of 140+ and fees varying accordingly

You will have to check with management quota.
Then there can be your chances.

Can.u please tell me the fees (at least a range) they charge in the colleges u mentioned above ??

The colleges fee structure is somewhere from 7-12 lacs aprox in the colleges mentioned above
