Answer 2

Given :

• In a class of 35 students.
• The number of girls 2/5 of the boys.

To Find :

• the numbers of boys in the class

Solution :

Let the number of boys be x

The number of girls be 2x/5

According to the question ;

Commonly in a classroom total students = boys + girls

Hence, x + 2x/5 = 35

5x + 2x / 5 = 35

7x/5 = 35

7x = 35 × 5

x = 35 × 5 / 7

x = 5 × 5

x = 25

Hence, number of boys = 25

It confusing because 2x/5 + 25 = 35 ??

Don't worry I will verify it.

Substitute x value in number of girls.

Hence, 2(25)/5 = 50/5 = 10

So, number of boys + number of girls = total students

25 + 10 = 35

So, 25 students are boys and 10 students are girls in the class.
