Show answer & explanation
Correct answer: C
Answer:
3 hours
Explanation:
Pump fills the tank in 1 hour
Time taken by Pump to fill due to leak = 1.5 hour
Therefore, in 1 hour, the amount of tank that the Pump can fill at this rate = 1 / (1.5) = 2/3
Amount of water drained by the leak in 1 hour = (1 – (2/3)) = 1/3
Therefore, the tank will be completely drained by the leak in (1 / (1/3)) = 3 hours
