The table shows the number of male and female teachers posted in the schools of five districts of a city.

What is the difference between the average number of male teachers in the five districts and the number of female teachers in the South district?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 88
The average of the male column is its total divided by 5; it is then compared with the female figure of South.
Male teachers: \(1650+1075+1280+1170+690=5865\)
Average \(\displaystyle=\frac{5865}{5}=1173\)
Female teachers in South = 1085
Difference \(=1173-1085=88\)
