TAPMI Manipal has already released their cutoffs for various entrance exams. For GMAT one needs a minimum of 630 scores. But if you've appeared for other exams like CAT or XAT you can get a call if you have a minimum of 85 percentile there.
Moreover you have a work experience of 30 months which means if you'll be eligible for profile based shortlisting. But since your GMAT scores are far lesser than what is required you should try with other exams (if you've appeared for those exams and have a percentile above 80).
