Ten men take 4 days to complete the task of tarring a road. How many days would8 men take?

To solve this problem, we first need to understand the relationship between the number of workers and the time it takes to complete a task. In this case, the relationship is inversely proportional, meaning that as the number of workers increases, the time it takes to complete the task decreases.

Step 1: Find the total man-days it takes to complete the task.

We know that 10 men take 4 days to complete the task. So, the total man-days is 10 men * 4 days = 40 man-days.

Step 2: Find out how many days it would take 8 men to complete the task.

We know that the task takes 40 man-days to complete. So, if 8 men were to do the task, it would take 40 man-days / 8 men = 5 days.

So, 8 men would take 5 days to complete the task of tarring the road.
