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 cu.m , then the rise in the water level in the tank will be:

20 cm
25 cm
35 cm
50 cm

Correct Answer: 25 cm

Explanation:

Total volume of water displaced =(4 x 50) cu.m = 200 cu.m

Rise in water level = $\frac{200}{40 \times 20}$ =0.25m = 25cm
