Answer 3

To solve this problem, we can use the concept of "man-days." The term "man-day" refers to the amount of work one person can do in one day.

Given information:

• Two carpenters (2 stolyara) made 20 boxes in 5 days.
• We need to find out how many boxes can be made by 4 carpenters in 8 days.

First, calculate the total man-days required to make 20 boxes with 2 carpenters in 5 days: Total man-days = Number of carpenters * Number of days Total man-days = 2 * 5 = 10 man-days

Now, we know that 10 man-days were required to make 20 boxes. Let's find out the number of man-days required to make the same number of boxes with 4 carpenters in 8 days:

Total man-days = Number of carpenters * Number of days Total man-days = 4 * 8 = 32 man-days

Finally, we can calculate the number of boxes that can be made with 4 carpenters in 8 days using the concept of man-days:

Number of boxes = Total man-days / Man-days per box Number of boxes = 32 man-days / 10 man-days per box (as found earlier) Number of boxes = 3.2 boxes

Since we cannot have a fraction of a box, the answer is that 4 carpenters will make 3 boxes in 8 days.
