Answer 2

Answer :

›»› The age of sister are 14 years and the age of Arjun are 18 years.

Given :

• Arjun is 4 year older than his sister and the sum of their ages is 32 years.

To Find :

• What are their ages?

Solution :

Let,

The age of his sister be "x"

Arjun is 4 year older than his sister.

→ x + 4

Sum of their ages is 32

→ x + x + 4 = 32

Calculate between similar terms,

→ 2x + 4 = 32

Move the constant to right side and change the sign,

→ 2x = 32 - 4

Subtract 4 from 32,

→ 2x = 28

Divide both sides by the same number,

→ x = 14

Now, put the value of x in Arjun age

→ x + 4

→ 14 + 4

→ 18

Therefore,

• Age of his sister = x = 14 years
• Age of Arjun = x + 4 = 18 years

║Hence, the age of sister are 14 years and the age of Arjun are 18 years.║
