Answer 1

Step-by-step explanation:

Originally Answered: Pipes A and B can fill a tank in 5 hours and 6 hours respectively. Pipe C can empty it in 12 hours. If all the three pipes are opened together, then the tank will be filled in? 1/5 + 1/6 - 1/12 = 12/60 + 10/60 - 5/60 = 17/60 = Can fill 17 tanks every 60 hours with all pipes running.
