Ratio of boy to girl = 5/6 B/G = 5/6 and no of girls - no of boys = 5 so G - B = 5 G = 5 + B so 5/6 = B/5+B 6/5 = 5+B/B 6/5 = 5/B + 1 6/5 - 1 = 5/B 1/5 = 5/B B = 25 so G =5 + B G= 5 + 25 G =30 total students = B + G =25 + 30 =55

B/G = 5/6
and no of girls - no of boys = 5
so G - B = 5
G = 5 + B
so 5/6 = B/5+B
6/5 = 5+B/B
6/5 = 5/B + 1
6/5 - 1 = 5/B
1/5 = 5/B
B = 25
so G =5 + B
G= 5 + 25
G =30
total students = B + G =25 + 30 =55
