Question
There are 500 students in a college. 45% of them are
boys. Among the boys and girls, 35% and 50% respectively are interested in music. How many students are not interested in music?Solution
ATQ,
Total number of boys = 500 × 0.45 = 225
Total number of girls = 500 - 225 = 275
So, number of boys who do not like music = 225 × 0.65 = 146.25 ≈ 146
So, number of girls who do not like music = 275 × 0.5 = 137.5 ≈ 138
So, required number of students = 146 + 138 = 284
