B.Sc Maths honors from DU will be a better option against B.Sc computer science. Later you can choose any other subject of your choice after graduation. You will be eligible for IIT JAM after B.Sc maths even for MCA admission.

IIMs offers PGDM and there are no MBA degrees offered there. You need to crack CAT or GMAT, for admission. Those who have excellent scores are only called for interview stage.
