Firstly, let's get some of the facts right. An MBA is a post-graduate qualification and can be taken up only after you complete your graduation.
It is usually a two-year program whereas the Chartered Accountancy (CA) is a professional degree which can be started after you finish your 12th standard.
For completing your CA, you don't have to attend any college or be affiliated to any university. Instead, you are required to register yourself with the ICAI (Institute of Chartered Accountants of India).
B.Com and CA/MBA:
A majority of students take up CA studies as well as complete their B.Com. The B.Com is a graduation degree granted by the University whereas the CA is self-study based (or you may take external help through prep classes) and you can complete it at your own pace.
Considering the low success rate in the CA exams, if you're unable to clear it, at least you'd be in a position to complete your graduation (B.Com) and later opt for any post-graduation program including an MBA. There are many students who may complete their CA and then also plan for an MBA some time later after a few years of working.
For graduates intending to study in an international MBA program, there are many international business schools accepting candidates with 15 years of college education.
The Chartered Accountant designation is a highly respectable one, especially if you have cleared it all in the first attempt.
CAs may start their own practice after gathering some experience or opt to work with other reputed Chartered Accountants firm.
The choice is yours whether you are comfortable working in a small or mid-size private practice, auditing and consulting firms, the banking or the corporate sector. You may get a chance to work with the Big-4 or join any multinational organisation (MNC).
Almost every huge organisation has an Accounts or Finance department and its up to you to decide where to apply.
In addition to auditing, taxation, financial accounting, compliance with various regulations or cost accounting which you may already be conversant with during your articled training, there is a lot more knowledge and skills youll pick while on your job.
Its purely based on your interest and the area you wish to work in. The scope of work for a CA is mainly in the field of finance and accounting area whereas MBAs have more diversity to choose from.

Hii Prosen,
See in marketing (core marketing profile/hardcore sales profile), job opportunity is there but mainly in hardcore sales as we know a perfect salesman always has a job in market but job sustainability depends upon the job profile.
In finance (core finance /sales of financial products), here also ample number of profile of financial sales are available (relationship manager, insurance, mutual fund, sales corporate and credit sales) which may be target oriented and a few number of profile core finance profiles (investment banker, research, derivative analyst, credit analyst). It is better to have 55-60 percent up to graduation for core finance but sustainability is higher in this profile.
I would request you to choose college through CAT higher score. It is an adverse fact that a few MAT level colleges can give you a secured sustainable job profile; rest others have the job profile which have 'hire and fire' strategy, and CTC/package is shown high but in hand salary may be poor. Be sure with CAT higher score or try BIMTECH-Noida or Christ- Bangalore. Sustainability is relatively good, especially in BIMTECH as their intake students is also low. If possible, tell us about your interested job field (core finance/ financial product sales/hardcore sales /marketing-sales/ HR) for a better guidance. Don't judge a college by CTC/package/100% placements and try to take a LinkedIn alumni tour and chat with them to get the exact average scenario. If this information is helpful, kindly up vote.
