Assuming you do dual specialisations in Marketing and Finance, you degree will have following wordings: "MBA with Specialisation in Marketing and Finance".

The better one is VIT-Vellore because it is widely preferred by the students for B.Tech and CSE. SRM is also good but if you get VIT go for it.
Both are good but the fee structure is a little high as they are private universities.
Salary packages depend on the candidate's skills and also the companies that offer core jobs. The candidates should have some additional skills to get placed easily.

You can apply for IPMAT. It's for the course IPM (Integrated Programme in Management) offered by IIM-Indore.
