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?

600

Total number of girls in K & M = \(\frac{13 + 7 }{100}\) × 6000

= 1200

Average number of girls in K & M = \(\frac{1200}{2}\) = 600
