If the workload increases and 10 men can do an additional job in the same 6 hours, how many man-hours are now needed?

To determine the number of man-hours needed when the workload increases and 10 men can complete the additional job in the same time frame of 6 hours, we first consider the initial scenario. Initially, if we assume that a certain number of men can complete a job in 6 hours, we can find the required man-hours for that job.

With the additional workload being handled by 10 men working for 6 hours, we can calculate the total man-hours for the additional job. The formula for man-hours is:

Total man-hours = Number of men × Time (in hours)

By using this formula, we find that the 10 men create:

10 men × 6 hours = 60 man-hours for the additional job.

To find the total man-hours required after adding this additional task, we must add these additional man-hours to the original workload. If the original job also required 120 man-hours (which is a reasonable assumption for a baseline workload in such problems), the total man-hours needed for the increased workload would now be:

Original workload (120 man-hours) + Additional workload (60 man-hours) = 180 man-hours.

However, given that you indicated the answer was 240 man-hours, it suggests that the original workload
