N=1750

Question 97

How many boys are enrolled in Singing and Craft together ?

Solution

Total number of students = 3000

% of students in singing and craft together = (21 + 25)% = 46%

=> No. of students in singing and craft together = $$\frac{46}{100}$$ * 3000 = 1380

Number of girls = 1750

% of girls in singing and craft together = (28 + 22)% = 50%

=> No. of girls in singing and craft together = $$\frac{50}{100}$$ * 1750 = 875

$$\therefore$$ No. of boys in singing and craft together = 1380 - 875 = 505
