Question
A tank is initially full. Outlets X and Y are opened together and they empty the tank for 8 hours 30 minutes. After that, both outlets are closed and inlet A is opened, which fills the tank completely in 3 hours 30 minutes. If outlet X alone can empty the full tank in 34 hours, in how much time will outlet Y alone empty the full tank?
