Question

The number of boys in a school is twice as number of girls. If number of boys are $500$ then find number of girls.

Answer 1

Let the number of girls $=\mathrm{x}$

According to the question, the Number of boys $=$Twice the number of girls

⇒Number of boys $=2\mathrm{x}$

⇒ $500=2\mathrm{x}$

or $2\mathrm{x}=500$

⇒ $\mathrm{x}=\frac{500}{2}=250$

Thus, there are $250$ girls in the school.
