A tank contains 500 liters of water in which 500 grams of salt is dissolved. Brine containing 5 grams of salt per liter is pumped into the tank at the rate of 2 liters per minute. The well stirred solution is then pumped out at a rate of 3 liters per minute. Find the amount of grams of salt in the tank when the tank contains 200 liters of brine.
