An electric pump can fill a tank in 4 hours.
A leak in the tank, it took hours to fill the tank.
Calculation:
Net, time taken by the leakage to empty a completely filled tank = t hours
According to the question,
1/4 - 1/t = 2/9
⇒ 1/t = 1/4 - 2/9
⇒ 1/t = (9 - 8)/36
⇒ 1/t = 1/36
⇒ t = 36 hours
∴ In 36 hours the leakage will empty a completely filled tank.
