Yes you are eligible for Mba as you have completed your graduation  . But you have to give an entrance exam called Cat  and also other exams  like Xat , Snap , Nmat etc : which is for private universities but Cat is a common entrance exam valid all over India . If you have  minimum 50% in graduation then you are eligible to apply for Cat entrance exam . After you give cat exam and score good marks you can get admission in any Mba college.  All the best
