Hey Prashant

Basically the salary pay is almost similar to all these courses i.e around 2-5 lakhs,If you do your postgraduation then the pay scale will increase.Important thing is that whatever you do you should gain complete knowledge about it which will help you in getting a good job that offers a good package but the suggestion is you should opt BCom if you are good at accounts,BBA if you are good at management and ba if you are good at economics(assuming that you may choose Economics Honors in BA) 

Hope the answer was helpfull

Thank You
