Explanation:
Let's solve step by step:
- Let the number of boys be 11x and girls be 15x (as per the ratio 11:15).
- It's given that girls are 200 more than boys: 15x - 11x = 200.
- So, 4x = 200 ? x = 50.
- Number of boys = 11x = 11 × 50 = 550.
Checking the options:
- Option 1: 550 (Matches our calculation)
- Option 2: 750 (Does not match)
- Option 3: 506 (Does not match)
- Option 4: 605 (Does not match)
Hence, the correct answer is option 1: 550.
