Question
The time taken to fill an empty tank completely when inlet A and outlet X are opened together is 6 hours 40 minutes less than the time taken by inlet B and outlet W together. Given that inlet A alone fills the tank in 4 hours, inlet B alone fills it in 8 hours, and outlet X alone empties the tank in 34 hours, how much time will outlet W alone take to empty the full tank?
