Show Answer

Answer:

Correct Answer: A

Solution:

Water flowed through pipe in $ 1h=\pi r^{2}h $
$ =\frac{22}{7}\times \frac{7\times 7}{100\times 100}\times 5000=77,m^{3} $ Required volume of water in tank $ =\frac{50\times 44\times 7}{100}=154,m^{3} $

$ \therefore $ Time taken to fill the tank $ =\frac{154}{77}=2,h $
