Problem Analysis

We are given that there were 160 children participating in a chess tournament, and the number of boys was three times the number of girls. We need to determine the number of boys and girls participating in the tournament.

Solution

Let's assume the number of girls participating in the tournament is x. According to the problem statement, the number of boys is three times the number of girls, so the number of boys is 3x.

The total number of children participating in the tournament is given as 160. Therefore, we can write the equation:

x + 3x = 160

Simplifying the equation, we get:

4x = 160

Dividing both sides of the equation by 4, we find:

x = 40

So, the number of girls participating in the tournament is 40, and the number of boys is three times that, which is:

3 * 40 = 120

Therefore, there were 120 boys and 40 girls participating in the chess tournament.

Answer

There were 120 boys and 40 girls participating in the chess tournament.
