Answer:
There are 300 girls left.
Explanation:
The ratio of boys to girls is 4:3.
Let the Number of boys = 4x
Number of girls = 3x
After 160 boys left , the ratio will be
[tex]\frac{(4x - 160)}{(3x)} =\frac{4}{5}[/tex]
solving for x.
5(4x - 160) = 4(3x) (cross multiplying)
20x - 800 = 12x
8x = 800
x = 100
substituting the value of we get
4x = 400 boys
3x = 300 girls
