Hello,

Getting a seat through management quota especially in reputed and top colleges like CBIT will cost you a lot. Management quota is preferred when the eligibility is not met. So, here your rank won't be considered or your rank won't impact the fee structure. The fees will vary from  1.3L to 1.8L per annum. (This is the fee structure for 2020 management seats in CBIT, there are chances of small changes in the amount).

Hope this helps. Thank you.
