Different universities have different criteria. Thus, some universities allow pursuing MCA after BBA if the student had studied Mathematics or Statistics or Business Maths or Business Statistics as one of the subjects in graduation or 10+2 level. So, I can recommend you some of the universities like Lovely Professional University, Christ University, JNU and University of Delhi which may allow you to pursue MCA if one of the given criteria is satisfied.

You can do it from the school of open learning it will not cost you high and you got the degree of DU. Hardly you have to pay 4 to 5 thousand in a year or less.
