The table given below shows the number of male teacher and female teachers in 5 schools.

Schools Male teachers Female teachers
J 180 240
K 240 210
L 210 60
M 150 30
N 90 90

A1 = The average number of female teachers in all the 5 schools.

A2 = The average number of male teachers in all the 5 schools.

What is the value of (A1 + A2) ?

Options:

300

48

126

174

Correct Answer:

300

Explanation:

A1 = The average number of female teachers in all the 5 schools.

=  \(\frac{240 + 210 + 60 + 30 + 90 }{5}\)

=  \(\frac{ 630}{5}\)

= 126

A2 = The average number of male teachers in all the 5 schools.

=  \(\frac{180 + 240 + 210 + 150 + 90 }{5}\)

=  \(\frac{ 870}{5}\)

= 174

Now , ( A1 + A2 ) = 126 + 174 = 300
