I think your question is incomplete or has an earlier thread attached to it because there is no way that someone can tell you your score without knowing any basis of it. Please elaborate.

Find out your weak areas ie. the subjects / topic, etc. in which you could not score or were confused while answering. Focus on them while preparing now. Evaluate your speed of answering the questions. Work on it through mock exercises. Enhance your logical reasoning power. Spend some time studying in groups and taking part in discussion and asking each other relevant questions. Increase your study time.

Dear,
With this percentage in graduation, you won't get best B-School of India. So, according to me, you should upgrade your percentage in Master degree and than try for Top B-School.
And you should appear for CAT, MAT, NMAT, XAT or GMAT and then try for B-School selection process.
All the best.
