Question

In professor shannon's economics class there are 12 male students. females represent 60% of the class total. how many students does professor shannon have in his economics class?

Answer 1

he has 30 students in his class because 40% of the class is boys and there is 2.5 40% in 100% so we do 12 x 2.5

Answer 2

Answer:

There are total 30 students in the class.

Step-by-step 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. $x=\frac{12}{0.4}$

i.e. x = 30

Thus, there are total 30 students in the class.
