See Management quota seats are present in most private colleges. Now if you want admission in management quota then the fees are made 30-40% greater than the actual fees i.e., say you want to take admission in a college where for BTech it charges Rs. 50,000 per semester then you will have to pay around Rs 70,000 per semester. Now depending on the college and the terms the range may vary. SO you have to contact the college you want to take admission in and get it discussed, they will provide you all the details.

I hope this answer helps. All the very best for your future endeavors!
