Number of boys (nb) = 250
Number of girls (ng) = 150
Total number of boys and girls (T1) = nb + ng = 250 + 150 = 400
Percentage of boys that palys football = 60%
Number of boys that plays football (nbf) = 60% * nb = 60/100 * 250 = 150
Percentage of girls that plays football = 40%
Number of girls that plays football (ngf) = 40% * ng = 40/100 * 150 = 60
Total number of boys and girls that plays football (T2) = nbf + ngf = 150 + 60 = 210
Thus, the percentage of girls and boys that plays football = T1/T2 * 100
= 210/400 * 100
= 52.5%
