It takes 8 men to build a fence in 9 days so how long it would take 3 men to build the same fence?
fence represents 72 mandays of effort.
72mandayseffort=men*time
men=3,then time=24 days
To figure out how long it would take 3 men to build the same fence, we need to use the concept of man-days.
Let's first calculate the man-days required to complete the fence by 8 men in 9 days:
Man-days = Number of men * Number of days
Man-days = 8 men * 9 days
Man-days = 72 man-days
Now, we can determine how long it would take 3 men to build the same fence:
Number of days = Man-days / Number of men
Number of days = 72 man-days / 3 men
Number of days = 24 days
Therefore, it would take 3 men 24 days to build the same fence.
