A) 6 min
B) 5 min
C) 10 min
D) 9 min
Correct Answer: B
Solution :
Volume of water flowing per second \[=\pi {{r}^{2}}h\] \[=\frac{22}{7}\times \frac{7\times 7\times 5}{10000}{{m}^{3}}\] \[=0.077\,{{m}^{3}}\] Volume of the tank \[=3\times 5\times 1.54\,{{m}^{3}}\] \[=23.1\,{{m}^{3}}\] \[\therefore \] Required time \[=\frac{23.1}{0.077}=300\,s\] = 5 minYou need to login to perform this action.
