Hi,
Fees also depends on college. Please specify the college.

In general, it is taken as one language and other 3 with the highest marks. But, these three should be subjects with more than 60 percent marks in theory. As far as I know in physical Science courses PCM is also taken into consideration.

Hons. in economics is better, but DU is much more better than Amity University. In my opinion, any course from DU is better, because it is a government university. The final choice would be yours.

Yes, definitely you are not eligible for economics hons, as it requires math as a subject in class 12th. Now, if you wish to study economics, then either you can go for BA Programme and take economics, as a subject or go for any hons course and take economics, as your Generic elective. If you take it as your GE for all four semester then you might get a minor in economics.
