You can find a link to the fee schedule of the Indian Patent Office here: http://ipindia.nic.in/ipr/patent/patent_FormsFees/index.htm. Please note that the fee schedule on the Indian Patent Office's website is linked to the corresponding forms in PDF format. The form needed for filing divisionals seems to be form 1, so the relevant fees should correspond with that.

But maybe an expert from India could shed some further light on this matter?
