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.

Ravi, its not so. It depends upon the company and its requirement. In case you end up doing MBA and go for placement drive, it makes no difference if there is another candidate who is B.Tech MBA if the basic eligibility required for the job is MBA or Masters. . What is important for recruiter is your knowledge, how you conduct yourself, how you perform in the interview.
Outside the college, even the name of your college makes a difference. If you have done a course/ degree from an institute having good reputation like it provides quality education, has good faculty, good placements, wonderful infrastructure then surely that is going to be an added advantage.
There are many good universities offering a wide range of courses to choose from. Most of them have good placement records and some even offer good scholarships to meritorious students.

Good luck.
