9. A tank initially contains 200 litres of fresh water. Brine containing 2.5 N/litre of dissolved salt runs into the tank at the rate of 8 litres/min and the mixture kept uniform by stirring runs out at the same rate. How long will it take for the quantity of salt in the tank to be 180 N? In 10 mins, determine the concentration of the salt in the mixture.
