Maths Eligibility

Sarash, there is no such criteria. For MBA, a candidate is to be graduate. Percentage may vary from university to university.
There are different ways of admission in MBA. Some institutes prefer CAT/XAT/ MAT scores only for admission to MBA course. And to appear for CAT/XAT/MAT etc student needs to have 50% in graduation. But eligibility criteria varies for various Management Institutes or Universities, they can take different %age in graduation along with CAT/ MAT/ XAT scores.
Another way of admission is internal tests or admission criteria of individual Management Institutes or Universities.
You can check the websites of some universities for more details.
Good luck.
