Answer:

There are total 30 students in the class.

Explanation:

Let the total number of students in class = x

Number of males in the class = 12

Number of females in the class = 60% of Total students = 60% of x = 0.6x

So, we get that,

Number of males + Number of females = Total students

i.e.
12+0.6x=x

i.e.
12=x-0.6x

i.e.
12=0.4x

i.e.
x=(12)/(0.4)

i.e. x = 30

Thus, there are total 30 students in the class.
