Answer 3

Problem Analysis

We are given information about three departments and the number of workers in each department. The first department has three times as many workers as the second department, and the third department has 11 more workers than the first department. We need to determine the number of workers in each department.

Solution

Let's assume the number of workers in the second department is x.

According to the given information: - The first department has three times as many workers as the second department, so it has 3x workers. - The third department has 11 more workers than the first department, so it has 3x + 11 workers.

To find the values of x, 3x, and 3x + 11, we can set up the following equation: x + 3x + (3x + 11) = 137

Simplifying the equation: 7x + 11 = 137

Subtracting 11 from both sides: 7x = 126

Dividing both sides by 7: x = 18

Now we can find the number of workers in each department: - The second department has x = 18 workers. - The first department has 3x = 3 * 18 = 54 workers. - The third department has 3x + 11 = 3 * 18 + 11 = 65 workers.

Therefore, there are 18 workers in the second department, 54 workers in the first department, and 65 workers in the third department.

Answer

There are 18 workers in the second department, 54 workers in the first department, and 65 workers in the third department.
