Find the difference in average of male teachers of all 5 districts to the female teachers of district South?
Answer & explanation
Correct answer: option 1
Total male teachers of all 5 districts = 1650 + 1075 + 1280 + 1170 + 690 = 5865
Average = \(\frac{5865}{5}\) = 1173
Female teachers in South district = 1085
Difference = 1173 - 1085 = 88
