Question

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: 20 cm 25 cm 35 cm 50 cm

Answer 1

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

Rise in water level = (200/40×20)=0.25m = 25cm
