| 50 men took a dip in a water tank 40 m long and 20 m broad on a religious day. If the average displacement of water by a man is \[4\,\,{{m}^{3}},\]then the rise in value level |
A) 20 cm
B) 35 cm
C) 25 cm
D) 50 cm
Correct Answer: C
Solution :
| Total volume of water displaced |
| \[=(4\times 50)\,\,{{m}^{3}}=200\,\,{{m}^{3}}\] |
| \[\therefore \]Rise in water level \[=\left( \frac{200}{40\times 20} \right)m=0.25\,\,m=25\,\,cm\] |
