ANSWER

30 students

EXPLANATION

There are 12 male students in the class.

That represents 40% of the class.

Let the total population of the class be x.

So, that means that:

[tex]\frac{40}{100}\cdot\text{ x = 12}[/tex]

Now, we solve for x:

[tex]\begin{gathered} 40\cdot\text{ x = 12 }\cdot\text{ 100} \\ \Rightarrow\text{ x = }\frac{12\cdot\text{ 100}}{40} \\ x\text{ = }\frac{1200}{40} \\ x\text{ = 30 students} \end{gathered}[/tex]

There are 30 students in the class.
