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.

In which district is the number of male teachers more than the number of female teachers?

A. B only

B. D only

C. Both B and E

D. Both E and F

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

Clearly, the number of male teachers is more than the number of female teachers in B and E.
