Hello there,
Admissions in Hindu Colleges is through CUET, and if you check your CSAS PAHSE 1 Portal you will find the courses your are eligible for in accordance to subjects you've had in 10+2 as well as subjects you've chose in CUET.
However, if a student doesn't have Maths or Economics in his\her class 12th, then the student is not eligible for any course of these two subjects. If you have studied Economics and Mathematics as your additional subject, you are then eligible.
I hope this information is helpful to you.
