Cost arithmetic

Using the 1.7 rates, compute the itemised charges and the total in basis points of buy value for: (a) an intraday round trip of ₹5,00,000 in a stock (buy and sell at the same price); (b) the same trade taken as delivery, excluding the DP charge; (c) one lot of Bank Nifty futures (30 units) bought and sold at an illustrative 55,000.
