Question

The strength of a class is $$65$$, including $$30$$ girls. Find the ratio of the number of:
girls to boys

Answer 1

Given
Total strength of class $$ = 65 $$
Total strength of girls $$ = 30 $$
Hence, total number of boys in a class will be
Boys $$ = 65 – 30$$
$$ = 35 $$
The ratio of girls to boys will be as given below:
$$ 30: 35 = 30 / 35 $$
On calculating further, we get
$$ = \dfrac{6}{7} $$
$$ = 6: 7 $$
$$ \therefore \, $$ The ratio between girls and boys will be $$ 6 : 7 $$
