Question
In a class, the number of boys is equal to the number of girls. What was the total number of students if twice the number of boys as girls remain when 12 girls entered out?
Solution
The problem states that the number of boys is equal to the number of girls in the class. Let's denote this number as "x". So, the total number of students in the class is 2x (x boys + x girls).
The problem also states that when 12 girls leave the class, the number of boys is twice the number of girls that remain. This can be written as: x = 2 * (x - 12).
Solving this equation for x gives us x = 24.
So, the total number of students in the class was 2x = 2*24 = 48.
