Question
Out of 450 students in a school, 48% are boys. Among the
boys and girls, 25% and 30% respectively like drawing. What is the total number of students who do not like drawing?Solution
ATQ,
Total number of boys = 450 × 0.48 = 216
Total number of girls = 450 - 216 = 234
So, number of boys who do not like drawing = 216 × 0.75 = 162
So, number of girls who do not like drawing = 234 × 0.7 = 163.8 ≈ 164
So, required number of students = 162 + 164 = 326
