What is the salary for a person who has done his MBA???
It's totally based on where you study.
If you do it in esteemed institutions like iims and other major institutes you will definitely get more than 10 lakh per year.
If you do it in normal colleges you can get the salary what a b.tech. graduate can get.
So go for the best b-schools in the country.
And don't go for the MBA just for salary packages.
