A) 2
B) \[1\frac{1}{2}\]
C) 3
D) \[2\frac{1}{2}\]
Correct Answer: A
Solution :
| [a] Water flowed by the pipe in \[1\,h=\pi {{r}^{2}}h\] |
| \[=\,\,\frac{22}{7}\times \frac{7\times 7}{100\times 100}\times 5000=77\,{{m}^{3}}\] |
| Volume of expected water in the tank |
| \[=\,\,\frac{50\times 44\times 7}{100}=154\,{{m}^{3}}\] |
| \[\therefore \] Required time \[=\,\,\frac{154}{77}=2\,h\] |
