Hello Asif Raza,
It depends on you, but I will suggest you should opt for mechanical engineering because it is an evergreen field. Aeronautical also has a good scope, but it doesn't have much demand as compared to mechanical engineering. Mechanical engineering has more scope for future. In future, you can move opt for Masters in aeronautical engineering.

It will be between 20000 and 30000 rupees per month.

The best colleges to pursue B.Sc in mathematics are:
1. St. Xaviers College

3. Ramnarain Ruia College
Lots of career options are open for you, but you should be careful, and select the course as per your interest. Please do not give priority to any other factor than your own interest. Here are few options for you:
1. M.Sc (if you are interested in teaching)
2. MCA
3. MBA
4. Any other competitive exam for jobs like admin, services, banks, etc.
According to me, you should meet a good career counselor for personality and interest psychometric test. Apart from your personality test.
