  • Question
  • A pump can fill a tank with water in 2 hours. Because of a leak, it took 213 hours to fill the tank. The leak can drain all the water of the tank in:


  • Options
  • A. 7 hours
  • B. 8 hours
  • C. 12 hours
  • D. 14 hours

  • Correct Answer
  • 14 hours 

    Explanation

    If the total area of pump=1 part

    The pumop take 2 hrs to fill 1 part 

    The pumop take1 hour to fill 1/2 portion 

     

    Due to lickage  

    The pumop take 7/3 hrs to fill 1 part 

    The pumop take1 hour to fill 3/7 portion 

    Now the difference of area = (1/2-3/7)=1/14 

     

    This 1/14 part of water drains in 1 hour 

    Total area=1 part of water drains in (1x14/1)hours= 14 hours 

     

    So the leak can drain all the water of the tank in 14 hours. 

    Leak will empty the tank in 14 hrs
