Answer / guest
The maximum possible value of X is 13 minutes 20 seconds.
In one minute,
pipe A can fill 1/30 part of the tank.
pipe B can fill 1/24 part of the tank.
Thus, the net water level increase in one minute is
= 1/30 + 1/24
= 3/40 part of the tank
In order to keep the tank always empty, outlet pipe C should
empty at least 3/40 part of the tank in one minute. Thus,
pipe C can empty the full tank in 40/3 i.e. 13 minutes 20
seconds.
