minutes, respectively. Pipe C can empty half filled pool in 30 minutes. If all the pipes are opened together, then find the time taken to fill the empty pool completelySolution
Time taken by pipe C to empty the full pool = 30 × 2 = 60 minutes Let the capacity of pool = 120 units Number of units of water filled by pipe A alone in one minute = 120/30 = 4 units Number of units of water filled by pipe B alone in one minute = 120/40 = 3 units Number of units of water emptied by pipe C alone in one minute = 120/60 = 2 units Required time taken = 120/(4 + 3 – 2) = 24 minutes
