Hello Akshay,

Yes you can get a seat in Delhi University and if you have a good percentage than you can even opt for a better college like SRCC also. As there are plenty of colleges who offer B.A. (Hons) Economics and the admission to this course is totally merit based. So If you want to enroll yourself for this course in University of Delhi you should have a good percentage in your hand and Since you are going to change your stream therefore you will have to face the deduction in the percentage also and it is totally dependent on the college because every college has its own rules and regulations.

I hope I was able to clear your query and if you want you can ask me anything regarding this topic in the comment section.

I wish you lots of luck and hope you do well in future.
