The prompt

Using the table above: cement company A wants to buy rival B in one Indian state. Cement is heavy and costly to move far, so the relevant market is local. Company A expects INR 300 crore a year of synergies (savings from combining). Work out the HHI before and after, the change, and what that means for the deal.
