Answer 2

Answer:

36 men

Step-by-step explanation:

length of pool(l): 24m

breadth of pool(b): 15m

height displaced by 1 man : 1cm or 0.01 m

also, volume displaced by 1 man : 0.1 m^3

LET NO. OF MEN BE Y

therefore,

volume of water displaced by y men = 0.1y= y/10 m^3

volume of displaced water :-

0.01 X 24 X 15 = y/10

1 X 24 X 15 X 10 / 100 = y

360/10 = y

36 = y

hence 36 men are there in pool
