Question : Two pipes A and B can fill a tank in 12 minutes and 24 minutes, respectively, while a third pipe C can empty the full tank in 32 minutes. All three pipes are opened simultaneously. However, pipe C is closed 2 minutes before the tank is filled. In how much time (in minutes) will the tank be full?
Option 1: 9
Option 2: 10
Option 3: 12
Option 4: 8
Correct Answer: 10
Solution : LCM of 12, 24 and 32 is 96 The capacity of the tank = 96 unit Efficiency of pipe A = $\frac{96}{12}$ = 8 unit/min Efficiency of pipe B = $\frac{96}{24}$ = 4 unit/min Efficiency of pipe C = $\frac{96}{32}$ = – 3 unit/min Combined
