12 hours for the remaining 2/3 of tank to be filled. If it is asked total fill the tank it will be 16 hours. Assume the two pipes fill at 18 units and 12 units per hour and the tank capacity is 360 units. After 120 units filled up the leak developed drains 1/3 of combined out put that is 10 units iutnof 30 units. The net output of both the pipes after one third tank is gilled is 20 units. 2/3 of tank is to be filled so it will take 12 hours fill 240 units. But over all it will take 12+ 4 = 16 hours to fill the tank completey
