An open tank with a 200L capacity is half-filled with pure water. A salt solution with a concentration of 10g/L is poured in at the rate of 15L per hour. At the same time, 10L are siphoned from the tank every hour. As usual, assume that the salt is mixed instantly and perfectly throughout the tank. How much salt is in the tank after 50hrs?
