Question
There are 1000 students in a school where the boy to girl
ratio is 2:3. If 18% of boys and 12% of girls did not clear the final exam, find the total number of students who failed.Solution
ATQ,
Number of boys = (2/5) × 1000 = 400
Number of girls = (3/5) × 1000 = 600
Required number of students = 0.18 × 400 + 0.12 × 600 = 72 + 72 = 144
