25 men complete a job in 60 hours.How long will it take 20 men to complete the same job?
The answer to this question
60/25 = x/20
Solve for x.
75hours
To answer this question, we can use the concept of man-hours, which is the amount of work completed by one person in one hour.
Given that 25 men complete the job in 60 hours, we can calculate the total man-hours required to complete the job. This can be done by multiplying the number of men by the number of hours:
Total man-hours = 25 men * 60 hours = 1500 man-hours
Now, we need to calculate how long it would take 20 men to complete the same job. We can divide the total man-hours by the number of men:
Time = Total man-hours / Number of men
Time = 1500 man-hours / 20 men
Simplifying this equation gives us:
Time = 75 hours
Therefore, it would take 20 men approximately 75 hours to complete the same job.
