Hello Anup,
Any Bachelor's degree will do in order to pursue your MBA from an IIM. However, ensure that the degree (B.Sc, BMS, B.Com, etc.) is given from a reputed and/or Govt. approved University.

To get admission in IIMs, you need to clear CAT. You need to score at least 97 percentile in CAT to get a call from IIMs. A good academic/work profile will definitely get you in IIMs.

For ranking you need to check Times of India Education as it would provide you the idea for top B-schools.

As a general candidate 90 percentile with similar marks in all sections to meet sectional cut off criteria can get you a call for interview in IIM-Ahmedabad. Higher percentile will be better.
