A pump can be operated both for filling a tank and for emptying it. The capacity of the tank is 2400 m3. The emptying capacity of the pump is 10m3 per minute higher than its filling capacity. Consequently, the pump needs 8 minutes less to empty the tank than to fill it. Find the filling capacity of the pump.	Choose the correct answer
A) 45 m3/min
B) 40 m3/min
C) 50 cubic metre per minute
D) 55 m3/min
E) None of these
2400/x - 2400/x+10=8,solving this we get x,   =50m3/min   Answer: 50 cubic metre per minute
