The table given below shows the number of male teacher and female teachers in 5 schools.
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) ? |
300 48 126 174 |
300 |
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 |
