1. Study the following pie-chart and bar graph and answer the questions that follows:
Percentage-wise distribution of Teachers in 6 Districts.

Number of males in each district out of 4500 Teachers.

What is the ratio of the number of male teachers in District C to the number of female teachers in District B?

A. 11 : 15

B. 15 : 11

C. 15 : 8

D. 30 : 13

Solution:

\begin{aligned} Total number of teachers in: \\ A → \frac{14}{100} \times 4500 = 630 \\ B → \frac{16}{100} \times 4500 = 720 \\ C → \frac{28}{100} \times 4500 = 1260 \\ D → \frac{15}{100} \times 4500 = 675 \\ E → \frac{21}{100} \times 4500 = 945 \\ F → \frac{6}{100} \times 4500 = 270 \end{aligned}

	A	B	C	D	E	F
Males	200	400	600	100	500	100
Females	430	320	660	575	445	170

(Number of male teachers in C) : (Number of female teachers in B)
= 600 : 320
= 15 : 8
