Hi Ravi,
If you are really good in numbers then statistics could really good field.
Remember a degree from INDIAN STATISTICAL INSTITUTE could do wonders to your career and they offer some of the most highly paid jobs in and around the world but remember getting into ISI is not such an easy task.
You can also opt for Engineering not necessarily CSE other departments like electrical, civil, mechanical from good college.
If you are really passionate about mathematics you can pursue an honours course. It will be great of you want to get into academics. Same goes for physics. There are several good institutes in India who have their own selection procedure for their courses.
But above all do what you like and what you want, don't blindly follow any advice, your inner calling is your actual friend follow its advice it will never fail you.
good luck!
