- The total candidates can be divided into boys and girls.

- 40% of candidates are girls, meaning 60% are boys.

- Let the total number of candidates be \( x \).

- Then, the number of boys is \( 0.6x \) and girls is \( 0.4x \).

- 35% of the boys failed, so 65% of the boys passed.

- If 585 boys passed, then \( 0.65 \times 0.6x = 585 \).

- Solving for \( x \), we get \( x = 1500 \).

- Thus, there are 600 girls (0.4 * 1500).

- 20% of the girls failed, so 80% passed.

- The number of girls who passed is 0.8 * 600.

- Hence, 480 girls passed.

- The correct number of girls who passed is 480.
