Total numbers of teachers $=4500$

The numbers of female teachers in District $D$ is approximately what percent of the total number of teachers (both male and female) in District $A$?

• A. $70$
• B. $90$
• C. $75$
• D. $80$

Answer 1

The correct option is B $90$

	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	$6\%\times 4500=270$	$100$	$170$

Female teachers in District $D=575$

Total teachers in District $A=630$

$\therefore \text{Required percentage}=\frac{575}{630}\times 100=91.26\approx 90$

Option D is correct
