A grandfather is ten times older than his granddaughter. He is also 54 years older than her. Find their present ages

Solution:

Let's form a linear equation for the given problem statement.

Let the granddaughter’s age be x years.

Therefore, grandfather’s age will be 10x years.

According to the question,

Grandfather’s age = Granddaughter’s age + 54 years

10x = x + 54

Transposing x to LHS, we obtain

10x - x = 54

9x = 54

x = 6

Hence, 10x = 60

Therefore granddaughter's age is 6 years and her grandfather's age is 60 years.
