Answer:

17

Step-by-step explanation:

From inspection of the given bar chart, the number of boys in each section is:

  • 8A = 16
  • 8B = 20
  • 8C = 16
  • 8D = 16

To find the average number of boys per section in class 8, sum the number of boys in each section and divide the result by 4.

[tex]\boxed{\sf Average=\dfrac{\textsf{sum of all the numbers}}{\textsf{amount of numbers}}}[/tex]

[tex]\implies \sf Average=\dfrac{16+20+16+16}{4}=\dfrac{68}{4}=17[/tex]

Therefore, there is an average of 17 boys per section in class 8 of Jagruti High School.

Answer:

17

Step-by-step explanation:

To find the average of something, we divide the total by the amount of sections/groups.

So we need to find the total number of boys and divide by the number of sections (4).

We can find the number of boys in each section by reading it off the chart:

8A: 16 boys

8B: 20 boys

8C: 16 boys

8D: 16 boys

So the total number of boys in class 8 is the sum of each section: 16+20+16+16=68

Divide this total by the number of sections (4) to get the average:

68/4=17

So the average number of boys per section in class 8 is 17.
