Answer 2

Answer:

168 men

Step-by-step explanation:

Let x be the length dug by one man in a day.

In 20 days the length dug by the 60 men will be given by :

x × 20 × 60 = 2000 m

From this we can get the value of x which is the length dug by one person.

1200x = 2000

x = 2000/1200

x = 1 ⅔ meters

From this we can get the number of men who can dig 4200 meters in 15 days.

5/3 × 15 × men = 4200

25m = 4200

m = 4200/25

m = 168 men.

The number of men will be 168 men.
