Question 74

The pie-chart shows the percentage-wise distribution of the number of students in five different schools P, Q, R, S and T. The total number of students in all five schools together is 10,500.

Study the pie-chart and answer the question.

The number of students in school R is what per cent of the total number of students in schools Q and T together?

Solution

Given, total number of students in all schools = 10,500

From the pie-chart,

Number of students in school R = $$\frac{12}{100}\times10500=1260$$

Number of students in school Q and T together = $$\frac{16+24}{100}\times10500=\frac{40}{100}\times10500=4200$$

$$\therefore\ $$Required percentage = $$\frac{1260}{4200}\times100=$$ 30%

Hence, the correct answer is Option D
