Correct Answer: 300
Solution :
A
1
= The average number of female teachers in all the 5 schools
= $\frac{(240 + 210 + 60 + 30 + 90)}{5}$

= $126$
A
2
= The average number of male teachers in all the 5 schools
= $\frac{(180 + 240 + 210 + 150 + 90)}{5}$
= $\frac{870}{5}$
= $174$
$\therefore$ A
1
+ A
2
= 126 + 174 = 300
