A tank can be filled by a pipe A in 3 hours and by pipe B in 5 hours. When the tank is full, it can be drained by pipe C in 4 hours. If the tank is initially empty and all three pipes are open, how many hours will it take to fill up the tank?

Result

t = 3:32 h Wrong answer

Step-by-step explanation:

a=3 h b=5 h c=4 h  z=a1+b1c1=31+5141=6020+60126015=6020+1215=60170.2833 1/h  t=1/z=1/0.2833=3.52941=3:32 h
