2. A tank contains 2,000 liters of brine. Brine containing 5N/liter of salt flows in at 10 liters/minute, and the mixture, kept uniform by stirring, flows out at the rate of 20 liters/minute. If the concentration of salt is 8N/liter at the end of 1 hour, how much was the concentration of salt at the beginning?
