Yes it's possible. But you'll have a hard time clearing the engineering entrance exams particularly chemistry. Also, you have to study basic chemistry in your first year. It's definitely possible but you better start studying chemistry. All the very best. Feel free to ask more questions.

For MBA courses, you can try looking at these options.
Memorial University of Newfoundland,
University Canada West,
Universit de Sherbrooke,
Trinity Western University.
There are other universities which offer Masters of science in management courses. Those are similar to MBA but different in course structure. If you are open to that course, then you will have a lot more options of universities within your budget.

Based on the specialisation that you will opt for, you can get a job at the Jr or middle management level in an organisation.

If you want to pursue CPL course, then you need to spend money.
Aviation is a very expensive course, and frankly, you need a minimum of 80 lakh rupees to become a pilot.
Best flying schools in India are:
Bombay flying club
Chimes aviation
Carver aviation
Gondia flying club
You can go for Indigo Cadet program, but in that also, you need to spend at least 60 lakh rupees for your training
All the best.
