  • Question
  • A booster pump can be used for filling as well as for emptying a tank. The capacity of the tank is 2400 m3 . The emptying capacity of the tank is 10 m3 per minute higher than its filling capacity and the pump needs 8 minutes lesser to empty the tank than it needs to fill it. What is the filling capacity of the pump?


  • Options
  • A. 50 m^3/min
  • B. 60 m^3/min
  • C. 72 m^3/min
  • D. None of these

  • Correct Answer
  • 50 m^3/min 

    Explanation

    Let the filling capacity of the pump be x m 3 /min. 

    Then, emptying capacity of the pump=(x+10) m 3 /min.  

    so, 2400 x - 2400 x + 10 = 8   ? x 2 + 10 x - 3000 = 0  

     

    ? x - 50 + x + 60 = 0   ? x = 50
