Problem Statement

The problem states that a daughter is 8 years old. The mother is 26 years older than the daughter, and the mother is also half the age of the grandfather. We need to find the age of the grandfather.

Solution

Let's break down the information given in the problem:

- Daughter's age: 8 years - Mother is 26 years older than the daughter - Mother is half the age of the grandfather

To find the age of the grandfather, we can use the information given. Let's denote the age of the grandfather as G.

From the given information, we can write the following equations:

1. Mother's age = Daughter's age + 26 2. Mother's age = 0.5 * Grandfather's age

We can set these two equations equal to each other and solve for the age of the grandfather.

Calculation

Let's substitute the values into the equations and solve for the age of the grandfather.

Equation 1: Mother's age = Daughter's age + 26 Equation 2: Mother's age = 0.5 * Grandfather's age

Substituting Equation 1 into Equation 2: Daughter's age + 26 = 0.5 * Grandfather's age

Rearranging the equation: 0.5 * Grandfather's age = Daughter's age + 26

Multiplying both sides by 2 to eliminate the fraction: Grandfather's age = 2 * (Daughter's age + 26)

Substituting the given value of the daughter's age (8 years): Grandfather's age = 2 * (8 + 26)

Calculating the expression: Grandfather's age = 2 * 34 Grandfather's age = 68

Answer

The age of the grandfather is 68 years.
