hello, my 10th and 12th score is above 80% but my graduation score is 55%only what bussiness schools for mba do i stand a chance to get in?

As you said your graduation percentage is 55 % , you are eligible to give CAT entrance exam . First don't think of admission in MBA , get good marks in CAT entrance exam from 95 percentile to 99 percentile . Most IIM'S have cut offs in that range , the admission for MBA is done on a point system basis , your 10th std , 12th std and graduation marks with your CAT  exam score with written ability test and personal interview and work experience (if any). Most of the top MBA college follow this criteria . So, i suppose you will do well in these exams and test , the following colleges you can get :

1) NMIMS UNIVERSITY (HAS SEPERATE ENTRANCE EXAM CALLED NMAT )

2) SYMBOISIS UNIVERSITY (  (HAS SEPERATE ENTRANCE EXAM CALLED SNAP )

3) IIM'S

4) MANIPAL UNIVERSITY

5) AMITY UNIVERSITY

6) FORE SCHOOL OF MANAGEMENT

10) IMRA ANAND

11) SP JAIN MUMBAI

12)KIIT SCHOOL OF MANAGEMENT
