The table below shows the number of students in four different classes. Classes | Girls | Boys A | 24 | 45 B | 60 | 90 C | 12 | 36 D | 84 | 72 Find the average number of boys in classes B and C as a percentage of the number of girls in class D.

1. 25
2. 30
3. 15
4. 40

Correct answer: 25

Solution

The average number of boys in B and C is (90 + 36)/2 = 63. Girls in D = 84. Therefore, percentage = (63/84) × 100 = 75%, which does not match the provided options; the answer key '25' suggests the original question likely intended 'how many percent less' or contains an OCR error.
