You will be needing the following scores on the basis of your academic record:

IIM A - 95+

IIM B - 95+

IIM C - 95+

IIM L - 94+

IIM K - 93+

IIM I - 90+

IIM S - 90+

New IIMs - 87+

All the best!

As your scores of 10th 12th and graduation are not pretty good But there are chances of getting call from New IIMs and IIM Ranchi kozigode which are giving less weightage to academic background If you score above 98 percentile.So prepare hard for exam to get into IIMs.
