Dear Vimal ,
According to KVPY Eligibility 2020 minimum Aggregate 75% (65% for SC/ST/PWD) in Maths and science subjects in class 10th exams. But you have not math subjects in 12th so you are not eligible for the Kishore Vaigyanik Protsahan Yojana .
Apart from that i have shared a link with you where you will get all information about this .
