B.Com

Eligibility Of the Bachelor of Commerce [B.Com]
The basic eligibility for admission to any of the B.Com. programs is a pass in Higher Secondary School Examination with Maths and English as core subjects. However, different universities release cut offs. Cut offs largely depend on the performance of students in the 10+2 exams and the number of qualified students applying to the course. Though, there is no work experience required for the course, students with work experience can also apply.

Admission Process for B.Com
In case of admission through cut-off percentage, students are required to secure equal to or more than the cut-off percentage. In case of Entrance Exams, a student needs to have secured a minimum percentage in 10+2 as prescribed by the university/college.

Narsee Monjee Institute of Management Studies, Mumbai

You must have studied Business Mathematics (aka Quantitative Methods) and Statistics in B.Com. Why don't you enroll in a course in Microsoft Power BI (Business Intelligence) in India to prepare yourself for a career in Data Analysis. Once you get a good knowledge in BI, apply for a MS in Business Analytics in USA. From the information I could gather, the following US universities accept applicants with a three year Indian Bachelor's degree.
University at Buffalo (SUNY)
Binghamton University (SUNY)
Columbia University in the City of New York
Northwestern University
University of North Carolina at Charlotte
Carnegie Mellon University
Tuck School of Business at Dartmouth
Wharton School, University of Pennsylvania
Zicklin school of Business, Baruch College (CUNY)
Darden School of Business, University of Virginia
Whitman school of Management, Syracuse University
Kent State University
Stony Brook University (SUNY)
Hunter College, City University of New York
Fordham University
Please visit the universities website to check whether or not they offer MS Business Analytics. Job prospects are great for a career in data analysis.

Your question does not say what programming languages or computer related subjects you studied in B.Com (Computer Applications). My presumption is that you must have studied C or C+ or Java and Database Management Systems. If that is the case, I will not advise you to study MBA (at this stage). Enroll in a course that will give you a strong knowledge in the following:
1) Statistics
2) Excel (2013 or 2016)
3) Visual Basic for Applications (VBA) for Excel
4) D3 (JavaScript) for Data Visualisation
5) Python for Data Analysis
6) R for Data Analysis
7) Microsoft Power BI (Business Intelligence) for Data Mining
8) SAS (Statistical Analysis System)
9) SPSS (Statistical package for Social Sciences)
M.Sc in Business Analytics will cover some important subjects listed above to prepare you for a career in Data Mining, Big Data, Data Analysis etc., where the opportunities are growing rapidly in India and abroad. Instead of studying MBA abroad, I will recommend M.Sc in Business Analytics. First, go through the syllabus of this course in various universities abroad, then study some the courses listed above that are NOT included in the syllabus. A good knowledge of Statistics and Excel is very important and basic requirement for a career in Data Mining, Big Data etc.
