#Anyone to help me this question#

If 6 men can take 8 hours to complete a job for 5 days. How long will 4 men finish the job if they use 6 hours?

The complete job takes 6*8*5=240 man-hours

240/(4*5) = 12 days for the 4 men.

Or, using ratios of the number of men and hours, it will take
5 * (6/4)*(8/6) = 12 days
That is, with only 4/6 as many men, it will take 6/4 as long;
working only 6/8 as many hours per day, it will take 8/6 as many days

To find out how long it will take 4 men to finish the job, we can use the concept of man-hours. Man-hours represent the total amount of work done by a person in one hour.

Given that 6 men can complete the job in 8 hours, we can calculate the total man-hours required to finish the job using the formula:

Total man-hours = Number of men * Number of hours

So, for 6 men to complete the job in 8 hours:

Total man-hours = 6 men * 8 hours = 48 man-hours

Now, we can determine how long it will take 4 men to finish the job using the formula:

Time = Total man-hours / Number of men

For 4 men to complete the job:

Time = 48 man-hours / 4 men = 12 hours

Therefore, it will take 4 men 12 hours to finish the job if they work together.
