Question

A class has total $60$ students with $x$ girls and $y$ boys. The number of girls is twice the number of boys. Express these statement in the linear equations form.

• A. $x+y=60,$ $x=2y$
• B. $x-y=60,$ $x=2y$
• C. $x+y=60,$ $x=3y$
• D. None of these

Answer 1

The correct option is A $x+y=60,$ $x=2y$

Given: Total number of students (i.e, boys $\left(y\right)$ and girls $\left(x\right)$) in the class is $60$.

Therefore,

$x+y=60$

And number of girls is twice the number of boys, so

$x=2y$

Hence option $A$ is correct choice
