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

$$\eqalign{ & \text{Total number of teachers in:} \cr & \text{A → } \frac{14}{100}\times4500 = 630\cr & \text{B → } \frac{16}{100}\times4500 = 720\cr & \text{C → } \frac{28}{100}\times4500 = 1260\cr & \text{D → } \frac{15}{100}\times4500 = 675\cr & \text{E → } \frac{21}{100}\times4500 = 945\cr & \text{F → } \frac{6}{100}\times4500 = 270\cr} $$

	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
