that depends on credit profile, limit exposure in cibil, existing relationship with bank, TRV, ITR etc.
Ideally, if you're earning 3L/pm then its upto 9L/pm -- this is norms and can be varied based on above features.
Try to send income docs to chennai address if it closes or around to that to get the required limit, again its need above parameters.
btw, whats your credit age in CIBIL?
