• D. $8:15$

Answer 1

The correct option is C $15:8$

	Total Teachers	Male Teachers	Female teachers
A	$14\%\times 4500=630$	$200$	$430$
B	$16\%\times 4500=720$	$400$	$320$
C	$28\%\times 4500=1260$	$600$	$660$
D	$15\%\times 4500=675$	$100$	$575$
E	$21\%\times 4500=945$	$500$	$445$
F	$6\%\times 4500=270$	$100$	$170$

Number of male teachers in District $C=600$

Number of female teachers in District $B=320$

$\therefore \text{Ratio}=600:320=15:8$

Option C is correct
