Question
Select the correct answerThe 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 students who are not scholarship holders isOptions60%30%75%78%
Solution
To solve this problem, we need to follow these steps:
-
Assume the total number of students in the school is 100. According to the ratio given, there are 60 boys and 40 girls.
-
20% of the boys are scholarship holders, which is 20/100 * 60 = 12 boys.
-
25% of the girls are scholarship holders, which is 25/100 * 40 = 10 girls.
-
So, the total number of scholarship holders is 12 boys + 10 girls = 22 students.
-
Therefore, the percentage of students who are not scholarship holders is 100% - 22% = 78%.
So, the correct answer is 78%.
