Problem Analysis

We are given the following information about the number of chairs in a classroom: - There are a total of 100 chairs. - The number of green chairs is twice the number of brown chairs. - The number of yellow chairs is equal to the sum of green and brown chairs, but 2 less than that sum.

We need to determine the number of chairs of each color.

Solution

Let's assume the number of brown chairs is x.

According to the given information: - The number of green chairs is twice the number of brown chairs, so the number of green chairs is 2x. - The number of yellow chairs is equal to the sum of green and brown chairs, but 2 less than that sum. So, the number of yellow chairs is (2x + x) - 2.

We know that the total number of chairs is 100. Therefore, we can write the equation:

x + 2x + (2x + x) - 2 = 100

Simplifying the equation:

6x - 2 = 100

Adding 2 to both sides:

6x = 102

Dividing both sides by 6:

x = 17

So, there are 17 brown chairs.

The number of green chairs is twice the number of brown chairs, so there are 2 * 17 = 34 green chairs.

The number of yellow chairs is equal to the sum of green and brown chairs, but 2 less than that sum. Therefore, there are (17 + 34) - 2 = 49 yellow chairs.

Answer

There are 17 brown chairs, 34 green chairs, and 49 yellow chairs in the classroom.
