A Pump can fill a tank with water in 2 hours. Because of a leak, it took \(2\frac{1}{3}\) hours to fill the tank. The leak can drain all the water of the tank in:

A 14 hrs.

B 4 hrs.

C 7 hrs.

D 8 hrs.

Correct Answer: Option A

Solution:

\(\frac{{2 \times \frac{7}{3}}}{{\frac{7}{3} - 2}} = \frac{{\frac{{14}}{3}}}{{\frac{1}{3}}} = \frac{{14}}{3} \times 3\) = 14 hrs.
