5 men can complete a job in 4 days. In how many days can 10 men working at 1/4 of the previous rate complete the job?
so, if 5 men can do it in 4 days, then 10 men can do it in 2 days.
But if working at 1/4 the rate, it will take 8 days
or, (5)(1)(4) = (10)(1/4)(x)
"He ate his breakfast with relish, and this time nothing distracted his attention while he was eating. He gave 'Unce Bashir, who was waiting on him, such a beaming smile that the poor man felt rather alarmed and taken aback. Usually he would only look in his directions to give orders or ask questions, althought on most occasions he treated him fairly well."
Based on this excerpt, what is the most likely reason that Bashir is called "Uncle"?
A. The man is so happy that he perceives his servant as a loving family member
B. "Uncle" is an affectionate nickname
C. He is the man's mother's brother
D. Uncle is probably a non-literal title, like in English we might call someone "bro" even if they aren't our brother

To solve this problem, we can use the concept of man-days, which measures the amount of work done by a person in a day. Let's start by calculating the total man-days required to complete the job.
We are given that 5 men can complete the job in 4 days. This means that in one day, the work completed by 5 men is equal to 1/4th of the entire job. We can express this as:
(5 men) x (4 days) = 1 job
Now, let's calculate the total man-days required to complete the job using this information:
Total man-days = (Number of men) x (Number of days)
Total man-days = (5 men) x (4 days) = 20 man-days
Now, we need to find how many days it will take for 10 men, working at 1/4th of the previous rate, to complete the job. Since they are working at 1/4th of the rate, we can multiply the total man-days by 4 to take this into account:
Total man-days for 10 men = (Total man-days) x (Rate of work)
Total man-days for 10 men = 20 man-days x 4 = 80 man-days
Finally, we can find how many days it will take for 10 men to complete the job by rearranging the formula for total man-days:
(Number of days) = (Total man-days) / (Number of men)
(Number of days) = 80 man-days / 10 men = 8 days
Therefore, it will take 10 men, working at 1/4th of the previous rate, 8 days to complete the job.
