In a school, 40% of the students are boys, and the rest
are girls. If 75% of the boys and 80% of the girls passed an exam, what percentage of the total students passed the exam?Solution
Let the total number of students be 100. Number of boys = 40, number of girls = 60. Boys who passed = 75% of 40 = 30. Girls who passed = 80% of 60 = 48. Total students who passed = 30 + 48 = 78. Percentage of students who passed = 78%. Thus, the correct answer is 78% .
