The ratio of boys to girls in a class is 3:5. If there are 12 more girls than boys, how many students are there in the class?

✓ Correct Answer: Option B

Let the number of boys be 3x and girls be 5x. The difference is 5x - 3x = 2x. Given 2x = 12, so x = 6. Total students = 3x + 5x = 8x = 8 * 6 = 48.
