Answer 3

Problem Analysis

We are given that there are 43 athletes in a sports section. Out of these, 19 are involved in multiple sports, and the number of runners is 4 more than the number of jumpers. We need to determine the number of runners in the section.

Solution

Let's assume the number of jumpers is x. According to the given information, the number of runners is 4 more than the number of jumpers. Therefore, the number of runners can be represented as x + 4.

We also know that there are 43 athletes in total, and out of these, 19 are involved in multiple sports. So, the number of athletes involved in only one sport can be calculated as 43 - 19.

Now, we can set up an equation to solve for the number of jumpers (x):

x + (x + 4) + 19 = 43 - 19

Simplifying the equation:

2x + 23 = 24

Subtracting 23 from both sides:

2x = 1

Dividing both sides by 2:

x = 1/2

Since the number of athletes cannot be a fraction, we can conclude that there is no solution to this equation. Therefore, it seems that there might be an error in the given information or the problem statement.
