The ratio of the number of boys and girls in a school is 3 : 2. If 20% of the boys and 25% of the girls are scholarship holders, the percentage of the school students who are not scholarship holders is: Correct Answer 78

Ratio of the number of boys and girls in a school is = 3 : 2 or 30 : 20

Let number of boys = 30 and number of girls = 20

Total students = 30 + 20 = 50

Number of boys who did not get scholarship = 30 × (80/100) = 24

Number of girls who did not get scholarship = 20 × (75/100) = 15

Total number of students who did not get scholarship = 24 + 15 = 39

∴ Percentage of students who did not get scholarship = 39/50 × 100 = 78%
