One of the primary reasons not to work there! But then you do have to realize that the cost of living is a fraction of what it is in US. I think 30-50K is pretty much on the low-average end even for a new grad.
When I graduated from college in bangalore (2004) I was offered a salary that would translate to about 21K USD (but in INR of course).
So, you should probably look into it. Colleges such as RVCE (my alma mater) do publish median salaries and std. deviation every year on their website.
