A tank contains 400 liters of brine. Twelve (12) liters of brine, each containing 2.5 N of dissolved salt enter the tank per minute and the mixture, kept uniform by stirring, leaves at the rate of 8 liters per minute. If the concentration is to be 2N per liter at the end of 1 hour, how many newtons of salt were originally present in the tank?
