Question

The total number of boys and girls in a class is 60. If the number of girls is 10 more than boys, then how many boys and girls are there in the class?

• A. 25 boys and 35 girls
• B. 35 boys and 25 girls
• C. 40 boys and 20 girls
• D. 20 boys and 30 girls

Answer 1

The correct option is A 25 boys and 35 girls

Let the number of boys be $x$.
So, according to the given data the number of girls is $x+10$.

By given data,
The total number of boys and girls = 60
$\Rightarrow x+(x+10)=60$
$\Rightarrow 2x+10=60$
$\Rightarrow 2x=60-10$
$\Rightarrow 2x=50$
$\Rightarrow x=\frac{50}{2}\Rightarrow x=25$

So, the number of boys, $x=25$ and
the number of girls, $x+10=25+10$
$=35$.
