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?

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
