Is this possible that if I have get less than 50 percent marks in graduation. Admission any MBA college?

Some colleges can accept students with less than 50% marks but some would not. But most of the colleges have at least 45% eligibility criteria which you have already MET so no issue with it.

Unfortunately, since almost all the top-ranked colleges in India consider only those who have scored at least 50% marks in graduation, it is not possible to get admission in such colleges.

I am afraid most colleges insist on 50% marks at graduation level. I would advise you to either reappear for graduation and score more than 50% or pursue a job and after 3 + years of work experience enrol for a part-time MBA/ Executive MBA / distance MBA programme.
