Dear Anand Raja. the following information makes you clear.the average of 8.8L and 20% of the batch was offered packages of more than 10L per annum. and highest salary maximum salary went up to Rs.12.25 lakhs : Anna University this year through campus placement with a salary package ranging from Rs 15 lakh to Rs 24 lakh per year.
my advice is prefer Anna University as first option. then you can go for second option LIBA. all the best.

MBA is definitely a better career option because it opens multiple career options, whereas with MCom your career is restricted to Finance & Accounting only.
