Table shows district-wise data of number of teachers posted in colleges of city.
Find the difference of the average of all male teachers and average of all female teachers?
Answer & explanation
Correct answer: option 2
Sum of all male teachers = 1650 + 1075 + 1280 + 1170 + 690 = 5865
Average = \(\frac{5865}{5}\) = 1173
Sum of all female teachers = 2375 + 2650 + 1520 + 1085 + 850 = 8480
Average = \(\frac{8480}{5}\) = 1696
Difference = 1696 - 1173 = 523
