hello aspirant,

there's no fixed amount as what amount needs to be deposited for donation.

you are talking about the seat in the college via management quota and you have to visit the college office and get to know about it directly from the college administration.

do not get the admission done by this quota via a third part source or any sort of agent, you may get robbed as well.

visit the office, talk to the management, get some concession as there is no fixed amount.

hope that helps
