1. study the following pie chart and bar diagram and answer the following questions.
Percentage-wise Distribution of students in 6 Different Schools. Total number of students = 6000.

Number of Boys in Each School Out of 6000 Student

What is the ratio of the number of boys in school C, the number of girls in school B and the total number of students in school E?

A. 45 : 7 : 97

B. 43 : 9 : 97

C. 45 : 7 : 87

D. 43 : 9 : 87

Solution:

\begin{aligned} Number of students in: \\ A → \frac{12}{100} \times 6000 = 720 \\ B → \frac{9}{100} \times 6000 = 540 \\ C → \frac{26}{100} \times 6000 = 1560 \\ D → \frac{18}{100} \times 6000 = 1080 \\ E → \frac{29}{100} \times 6000 = 1740 \\ F → \frac{6}{100} \times 6000 = 360 \end{aligned}

Number of boys in:
A → 500
B → 400
C → 900
D → 600
E → 1200
F → 100

Number of girls in:
A → 720 - 500 = 220
B → 540 - 400 = 140
C → 1560 - 900 = 660
D → 1080 - 600 = 480
E → 1740 - 1200 = 540
F → 360 - 100 = 260

Required ratio
= 900 : 140 : 1740
= 90 : 14 : 174
= 45 : 7 : 87
