Hi Tanvi,
I understand that you have scored 86% in your class 10th and 95% in class 12 but have scored a graduation percentage of 15.5% and that you are inquiring about the score that you need to to achieve in order to get a call from Indian Institute of Management and so to answer your question you need to get a percentile of at least 99% otherwise you won't get a call from any IIM whatsoever and also be informed that since you have less percentage in your graduation marks does there is a chance that you might not get a call from the I am due to this fact.
Best wishes!
