Question

One day a third of the class is absent and 16 children are present. How many children are in the class when no one is absent? ( with steps)​

Answer 1

Given:

One day,

• A third of the class is absent.
• 16 children are present.

To Find:

• How many children are in the class when no one is absent?

Let us assume:

• Total number of children be x.

According to the question.

Absent + Present = Total students

↠ 1/3 of x + 16 = x

↠ x/3 + 16 = x

↠ 16 = x - x/3

↠ 16 = 3x/3 - x/3

↠ 16 = 2x/3

↠ 16 × 3 = 2x

↠ 48 = 2x

↠ 48/2 = x = 24

Hence,

• 24 children are in the class when no one is absent.

Answer 2

$\huge\mathfrak\red{Given :}$

• On a day third of class is absent.
• 16 children's are present.

$\huge\mathfrak\green{To \: Find :}$

• How many childrens are in the class when no one is absent.

• Let the total number of children be x.

According to the Question→

• Total students = Absent student+ Pesent a student

$x = \frac{1}{3} \times x + 16$

$x = \frac{x}{3} + 16$

$16 = x - \frac{x}{3}$

$16 = \frac{3x - x}{3}$

$16 = \frac{2x}{3}$

$16 \times 3 = 2x$

$48 = 2x$

$\frac{48}{2} = x$

$24 = x$

Hence,

• 24 students are present in the class when no one is absent.
