A pipe can fill a tank in 14 hours. Due to the leak in its bottom, the tank is filled in 16 hours. If the tank is full, then that leak can empty the tank in how many hours?
1). 112
2). 120
3). 108
4). 110
Part of tank filled by the pipe in one hour = 1/14
Part of tank filled by the pipe with a leak in its bottom in one hour = 1/16
Part of tank the leak can empty the tank in one hour = (1/14) – (1/16) = 1/112
∴ Time taken by the leak to empty the tank = 1/(1/112) = 112 days
