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