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

Answer: Option C

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

	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.
