I am presently drawing a salary of 15k including allowances life traveling expenses etc..I am 31ys,is it low?

I feel that is considerably low and your includes allowances as well, that means your in hand salary is less. If you want to get a better paying job I will advise you to do MBA from a good institution preferably under rank 35. So, after your 2 years of MBA you will definitely earn more than double your present salary which I don't think would be possible if you continue your current job.MBA is the future and believe me you will never regret your decision of doing MBA.And getting admission in MBA college of rank say 25-30 is not that difficult.
