A pipe can fill a tank in 2 hours. Because of a leak in the tank, the pipe takes 2 hours 40 minutes to fill the tank. The time the leakage takes to empty the full tank is :
- A 6 hours
- B 8 hours
- C 10 hours
- D 12 hours
Answer & Solution
Correct Answer
(B) 8 hours
Step-by-step Solution
Detailed explanation
\( \frac{1}{T_{leak}} = \frac{1}{T_{pipe}} - \frac{1}{T_{pipe+leak}} \) \( \frac{1}{T_{leak}} = \frac{1}{2 \text{ h}} - \frac{1}{2 \text{ h } 40 \text{ min}} \) \( \frac{1}{T_{leak}} = \frac{1}{2} - \frac{1}{8/3} \) \( \frac{1}{T_{leak}} = \frac{1}{2} - \frac{3}{8} \)…
