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 m3, then the rise in the water level in the tank will be:

A. 20 cm B. 25 cm
C. 35 cm D. 50 cm

• Total volume of water displaced = (4 x 50) m3 = 200 m3
  vol=l*b*h=40*20*h
  40*20*h=200
  h=0.25m=25cm
