Study the pie-charts carefully to answer the following questions.

Percentages of students enrolled in different activities in a school

N=3000

Percentage break-up of girls enrolled in these activities out of the total students

N=1750

Question 98

What is the respective ratio of number of girls enrolled in Swimming to the number of boys enrolled in Swimming ?

Solution

Total number of girls = 1750

No. of girls enrolled in swimming = $$\frac{14}{100}$$ * 1750 = 245

Total number of students = 3000

Total number of students enrolled in swimming = $$\frac{16}{100}$$ * 3000 = 480

=> No. of boys enrolled in swimming = 480 - 245 = 235

$$\therefore$$ Required ratio = 245 : 235 = 49 : 47
