The data given in the table shows the number of Boys and girls enrolled in three different streams in a school over 5 years. (2012 to 2020)

What is the difference between the average of the number of Boys in the Commerce stream for the 5 years and the average of the number of girls in the Arts stream for the 5 years?

8

Average number of boys in commerce = \(\frac{35 + 32 + 36 + 28 + 39}{5}\)

= \(\frac{ 170}{5}\)

= 34

Average number of girls in Arts = \(\frac{36 + 43 + 42 + 46 + 43}{5}\)

= \(\frac{ 210}{5}\)

= 42

Required difference = 42 - 34 = 8
