Solution

To solve this problem, we need to understand the concept of man-days which is a unit for a amount of work done by an individual in a day.

Step 1: Calculate the total man-days for the work If 10 men can do the work in 4 days, the total man-days for the work is 10 men * 4 days = 40 man-days.

Step 2: Calculate the number of days it would take for 8 men to do the work If 8 men were to do the same work, we would divide the total man-days by the number of men. So, 40 man-days / 8 men = 5 days.

So, 8 men can do the work in 5 days. Therefore, the correct answer is:

radio_button_unchecked 7 days

radio_button_checked 5 days

radio_button_unchecked 8 days

radio_button_unchecked 6 days
