I have done my graduation with 41% and have 7 years of work experience. Am I eligible to get admission for MBA?

Yes, you are eligible for doing MBA, though you have got the less percentage in your graduation, but the work experience you have is really excellent, so definitely if you have a good speaking skills you can get admission into better colleges.
