Question
In a school of 960 students, the ratio of boys to girls is
5:3. During the annual test, 20% of boys and 25% of girls did not pass. What is the number of students who failed the test?Solution
ATQ,
Number of boys = (5/8) × 960 = 600
Number of girls = (3/8) × 960 = 360
Required number of students = 0.20 × 600 + 0.25 × 360 = 120 + 90 = 210
