Problem Analysis

We are given that two masters work in a factory that produces Christmas tree ornaments. Both masters can paint the same number of ornaments in one hour. The first master worked for 5 days, 8 hours per day, while the second master worked for 4 days, 6 hours per day. Together, they painted a total of 1280 ornaments. We need to determine how many ornaments each master painted.

Solution

To solve this problem, we can calculate the total number of hours worked by each master and then use that information to find the number of ornaments painted by each.

Let's start by calculating the total number of hours worked by the first master. The first master worked for 5 days, 8 hours per day, so the total number of hours worked by the first master is: 5 days * 8 hours/day = 40 hours

Next, let's calculate the total number of hours worked by the second master. The second master worked for 4 days, 6 hours per day, so the total number of hours worked by the second master is: 4 days * 6 hours/day = 24 hours

Now, let's calculate the total number of ornaments painted per hour by both masters. We know that together they painted 1280 ornaments in a total of 64 hours (40 hours + 24 hours). Therefore, the number of ornaments painted per hour by both masters is: 1280 ornaments / 64 hours = 20 ornaments/hour

Finally, let's calculate the number of ornaments painted by each master. Since both masters paint the same number of ornaments per hour, we can divide the total number of hours worked by each master by the number of ornaments painted per hour by both masters.

The number of ornaments painted by the first master is: 40 hours / 20 ornaments/hour = 20 ornaments

The number of ornaments painted by the second master is: 24 hours / 20 ornaments/hour = 12 ornaments

Answer

The first master painted 20 ornaments, while the second master painted 12 ornaments.
