To be perfectly honest with you, many universities seem to label courses as either BA/BSc or MA/MSc in a rather arbitrary manner. In fact, various universities/courses in the UK don't even bother awarding such letters even though the course content is comparable. (instead you get MA (Hons), or MPhil, etc). In extreme circumstances the title of the degree (MA/MSc) simply comes down to academic discipline (BSc Science, BA Art), but social science courses (such as management) are such blends and hybrids that it's almost impossible to classify. You can get a science degree in history, and you can get an art degree in psychology. The UK lacks consistency outside of the obvious extreme examples (like I said, Master of Arts in Art, and Master of Science in Science). Social science is neither art nor science, so cannot be divided so simply. You may find that some courses try to be more scientific and also adopt the scientific-sounding MSc, but you could also find that similar courses have the title MA. The only thing that is important is the course content, and unfortunately the MSc/MA titles are not reliable indicators of such content.
I won't comment about reputation in India of the two universities since I (and nearly all) TSR users wouldn't have a clue (having never even visited the place).
