Science

Let me put down some of the verticals which people generally choose (as per popularity in descending order) :
Masters in Statistics or Mathematics or maybe some other one-year certification course in Statistics.
Actuarial Science (actuarial aspirants generally join actuarial society along with your graduation).
MBA
Corporate Job
Government jobs (Grade A)
Indian Statistical Services (ISS)
Defence services
Civil Services(rarely people go for civil services)
Government Jobs (Grade B)
SSC-CGL (Statistical officer)
RBI
Summing up all this, I must say people with fair knowledge of Statistics are in huge demand in the present scenario and this demand will remain there in upcoming few decades at least.

It is not necessary that you need to have maths in class 12 in order to pursue BBA in India.
There are some colleges like NMIMS School of Commerce, in which maths is compulsory for admission.
It is because the curriculum there is very exhaustive and requires quantitative and analytical skills.
Whereas some universities like Delhi University and Mumbai University do not require maths as a compulsory subject in class 12 for admission in BBA.
So, it is not necessary that one should have maths in class12 to pursue BBA in India, but it is always advisable to choose maths in class 12 (optional subject for PCB, commerce and humanities students) as it adds to your skills and opens up more opportunities.
