Problem

The bar graph below shows the numbers of boys and girls in Mrs. Kuwabara’s class. The percentage of students in the class who are girls is

$\textbf{(A)}\ 40\% \qquad\textbf{(B)}\ 15\% \qquad\textbf{(C)}\ 25\% \qquad\textbf{(D)}\ 10\% \qquad\textbf{(E)}\ 60\%$

Solution 1

We can first find the the number of girls in the class and the total number of students.

From the bar graph, we can see that there are $10$ girls and $15$ boys. This means that the total number of students is $10 + 15 = 25$.

We can then see that the percentage of girls in the class is:

$\frac{10}{25} \times 100\% = 0.4 \times 100\% = \boxed {\textbf {(A) } 40\%}$
