who passed in the examination.

630

210

550

840

- The total number of students in the class is 1500.

- 30% of 1500 are girls, which equals 450 girls.

- Subtracting the number of girls from the total gives us the number of boys: 1500 - 450 = 1050 boys.

- 80% of boys failed the exam.

- 20% of boys passed since 100% - 80% = 20%.

- Calculate the number of boys who passed: 20% of 1050 = 0.2 * 1050 = 210 boys.

- 210 is the correct number of boys who passed.

- Option 2, which says 210, is the correct choice.

Option 2: 210 is the right answer.
