The pie chart given below shows the number of girls in six schools: The total number of girls in all these six schools are 6000. Number of girls in a particular school is shown as percentage of total number of girls in all these six schools.
What are the average number of girls in school K and M?
Answer & explanation
Correct answer: option 2
Total number of girls in K & M = \(\frac{13 + 7 }{100}\) × 6000
= 1200
Average number of girls in K & M = \(\frac{1200}{2}\) = 600
