Question

There are 45 students in a class. 60% of the students are boys. Find the number of girls in the class.

Answer 1

$\texttt{Total Number of students in the class = 45}$

$\texttt{Number Of Boys = 60\% of 45}$

$\tt = \frac{60}{100} \times 45 = \frac{2700}{100} = 27$

$\texttt{So, number of girls = 45-27 = 18}$

$\texttt{Thus, there are 18 girls in class. }$

Answer 2

Step-by-step explanation:

Total students = 45

% of boys = 60%

No. of girls = ?

No. of boys = 45×$\frac{60}{100}$

= $\frac{45×6}{10}$

= 27

No. of girls = Total students - No. of boys

= 45-27

= 18
