Answer:
given that
40% = boy
let boys= y and girls = x
find ratio between x and y
students = y+x
100% = 40% + x
100% - 40% = x
x= 60%
the ratio between y and x 4:6 respectively
if 24boys then what is the no of girls
let.
We know that the ratio of y and x
4 : 6
24/4 = x/6
24×6 = 4x
144 = 4x
144/4 = x
x=36
