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

In which of the following schools is the total number of students equal to the number of girls in school E?

A. A

B. B

C. C

D. D

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

Number of girls in School E = 540
= Total number of students in B
