Question
In a school having 600 students, 55% are boys. Out of the
boys and girls, 40% and 35% respectively enjoy reading books. How many students do not enjoy reading books?Solution
ATQ,
Total number of boys = 600 × 0.55 = 330
Total number of girls = 600 - 330 = 270
So, number of boys who do not enjoy reading = 330 × 0.6 = 198
So, number of girls who do not enjoy reading = 270 × 0.65 = 175.5 ≈ 176
So, required number of students = 198 + 176 = 374
