If 10 men can finish a job in 6 hours, how many hours would it take for 1 man to do it alone?

To determine how many hours it would take for one man to complete the job alone, we start by calculating the total work done in terms of man-hours. If 10 men can finish the job in 6 hours, we multiply the number of men by the hours they work to find the total man-hours required to complete the job.

Total man-hours = Number of men × Time taken = 10 men × 6 hours = 60 man-hours.

This means that the job requires a total of 60 man-hours to complete. Since one man can do the job by himself, we divide the total man-hours by the number of hours that one man can work.

Time taken by 1 man = Total man-hours / Number of men = 60 man-hours / 1 man = 60 hours.

Now, let's consider the answer choices provided. The correct choice aligns with the calculation that indicates it would take 60 hours for one man to do the job alone, which is an important detail to highlight. The figure of 60 hours makes logical sense because we calculated it based on the total effort needed to complete the task divided by how many working hours one individual contributes. This systematic breakdown ensures that the solution is consistent with the principles of work
