Question

The number of boys in a school is $334$ more than the number of girls. If the total strength of the school is $572$, find the number of girls in the school.

Answer 1

Let the number of girls be $x$

Number of boys $=x+334$

total strength $=572$

$\Rightarrow x+x+334=572$

$\Rightarrow 2x+334=572$

$\Rightarrow 2x=238$

$\Rightarrow x=\frac{238}{2}=119$ girls
