Show answer & explanation
Correct answer: A
First, calculate School B students scoring 90-95%: 6% of 10,000 = 600. Girls ratio is 1:4, so girls = 600 * (1/5) = 120.
Next, calculate School D students scoring 95%+: 8% of 6,000 = 480. Girls ratio is 7:1, so girls = 480 * (7/8) = 420.
Finally, find the percentage: (120 / 420) * 100 ≈ 28.57%.
