B.E.

Hello Akshay,
BC quota is around 23% in most of the cases. The answer to your question is to be found using empirical and approximations. In IIT's, there are about 10000 seats and 1000 are for CSE. By the same logic, there are approximately 15 Lacs seats on all India basis and there should be about 1.5 Lacs seats for CSE. Out of these, approximately 23% would be under OBC. Best wishes to you.

Total fees of B.Tech. In Aerospace Engineering in Karunya Institute of Technology and Sciences, Coimbatore is INR 7.84 Lacs
