If a pipe fills a tank in 6 h, then what part of the tank will the pipe fill in 1 h?

A) \( \Large \frac{1}{3} \)
B) \( \Large \frac{1}{6} \)
C) \( \Large \frac{1}{4} \)
D) \( \Large \frac{1}{5} \)

Correct Answer:


B) \( \Large \frac{1}{6} \)

Description for Correct answer:
We know that, when a pipe fills a tank in m h, then the part of tank filled in 1 h

Here, m = 5 Required part of the tank to be filled in 1 h = \( \Large \frac{1}{m} \)

Here, m = 6

Therefore, Required part of the tank to be filled in 1 h = \( \Large \frac{1}{6}\ part \)
