There are $70$ student in class boys, girls ratio $4: 3$, how many are boy and girls?
Given: There are $70$ student in class boys, girls ratio $4: 3$.
To do: To find the number of boys and girls.
Solution:
As given ratio of the boys and girls $=4:3$
Total number of the students$=70$
Let $4x$ be the number of boys and $3x$ be the number of girls.
Therefore, Total number of students $=4x+3x=7x$
$\Rightarrow 7x=70$
$\Rightarrow x=\frac{70}{7}$
$\Rightarrow x=10$
Number of the boys$=4x=4\times10=40$
Number of girls$=3x=\times10=30$
