Question 1000054: In seventh class the number of girls is 1/4 times the number of boys. If the number of students in the class is 35, find the number of boys and girls in the class. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call boys and girls, b and g.
Here b + g = 35 and
g = (1/4)b or b = 4g
Substituting this we get
4g + g = 35
5g = 35
g = 7 girls
b = 28 boys
