Question
Pipe A and B can fill the pool in 30 minutes and 20
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 = 60 units Number of units of water filled by pipe A alone in one minute = 60/30 = 2 units Number of units of water filled by pipe B alone in one minute = 60/20 = 3 units Number of units of water emptied by pipe C alone in one minute = 60/60 = 1 units Required time taken = 60/(2 + 3 – 1) = 15 minutes
