A) 50 minutes
B) 50 minutes 12 seconds
C) 51 minutes 12 seconds
D) 51 minutes 15 seconds
Correct Answer: C
Solution :
Volume of water per minute \[=\pi {{\left( \frac{5}{2} \right)}^{2}}\times 10\times 100\times 10\] \[=\frac{25\times 100\times 100}{4}\pi \,\,m{{m}^{3}}\] Volume of conical vessel \[=\frac{1}{3}\,\pi .\,{{(200)}^{2}}.240\] \[\therefore \] Time taken \[=\frac{\frac{1}{3}\pi \times 200\times 200\times 240}{25\times 100\times 100\times \pi }\times 4\] \[=\frac{3840}{75}\] minutes \[=51\,\min utes\,\,12\,\text{seconds}\]
