Surya's age is twice his brother's age. The sum of their ages is 30. Find the ages of Surya and his brother​

Answer 1

SoluTion:

Let age of surya's brother be x and age of surya be 2x

According to question, Sum of their ages is 30.

x + 2x = 30

→ 3x = 30

→ x = 30/3

→ x = 10

Hence,

• Age of his brother = x => 10 years.
• Age of surya = 2x => 2 × 10 = 20 years.

Therefore, age of surya and his brother is 20 and 10 respectively.
