Firstly, you will have to check and confirm with the authorities whether they provide management quota admission or not. If they do, you must ask them the seats available and further eligibility. The criteria differs from college to college so it would not be right to comment any figure. Moreover the management quota fees too is something decided by college authorities. This is not something which is decided by any specific umbrella authority. So they will give you a better estimate of that.

Good luck!
