Solution:
In Ms. Perron’s class, 40% of the students are boys
There are 10 boys in the class
Let "x" be the total number of students in Perron class
From given,
40 % of total students are boys
Therefore,
40 % of x = 10
[tex]\frac{40}{100} \times x = 10\\\\40x = 1000\\\\x = 25[/tex]
Thus total number of students in Ms. Perron’s class is 25
