Maths is not compulsory in BA graduation degree at Delhi University.

In my opinion BA honours in economics is a better option.
It will include all aspects of economics. It will include mathematical and theoretical aspects of economics. It will include micro, macro, statistics, international economics, econometrics. It will be relevant in every field. It is an academic course. It is a vast course. BA business economics will focus more on the business aspects. It will include topics like consumers behaviour, producers equilibrium, demand and supply. It is a professional course. It is a specialised course.

B.Sc is more practical, and BA is more theoretical. B.Sc focusses more on mathematical aspects. It has more number of courses. A B.Sc degree should be your first choice. If you go for an honors course, you get a specialization in the final year.

It is very difficult. Maybe, you can try last cut off of the evening colleges for some not so popular programs. Don't target the morning classes. Or, maybe if you have sports quota, you can get admission.
