Best answer
Correct Answer - Option 4 : 28%

Calculation:

Total number of students = 6300

Number of boys = 5/9 × 6300

⇒ 3500

∴ number of girls = (6300 - 3500)

⇒ 2800

Number of boys enrolled in Painting = 621

Number of students enrolled in Quiz = 36% of 6300 = 2268

Number of girls enrolled in Quiz = 640

∴ number of boys enrolled in quiz = 2268 – 640

⇒ 1628

∴ Required percentage = 640/2268 × 100

⇒ 28.21% ≈ 28%

The total number of girls in Quiz is approximately 28% of the total number of students in Quiz.
