Explanation:
- We start with the ratio of boys to girls, which is 11:15.
- Let the number of boys be 11x and the number of girls be 15x.
- We know there are 200 more girls than boys, so we create the equation: 15x - 11x = 200.
- Simplifying, we get 4x = 200.
- Solving for x, we find x = 50.
- The number of boys, given by 11x, is 11 * 50 = 550.
- Option 1: 550
- Option 2: 750
- Option 3: 506
- Option 4: 605
