Problem Analysis

To solve this problem, we need to determine the age of the father given that the daughter is 12 years old, her age is one-third of her mother's age, and the mother is 4 years younger than the father.

Solution

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

1. The daughter is 12 years old. 2. Her age is one-third of her mother's age. 3. The mother is 4 years younger than the father.

Let's assign variables to the unknowns: - Daughter's age: D - Mother's age: M - Father's age: F

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

1. The daughter's age is one-third of her mother's age: D = (1/3)M. 2. The mother is 4 years younger than the father: M = F - 4.

To find the father's age, we need to solve for F.

Solution Steps

1. Substitute the value of M from equation 2 into equation 1: D = (1/3)(F - 4). 2. Substitute the given value of D (12 years) into the equation: 12 = (1/3)(F - 4). 3. Solve the equation for F.

Let's solve the equation to find the father's age.

Solution

Substituting the given values into the equation:

12 = (1/3)(F - 4)

To solve for F, we can multiply both sides of the equation by 3:

3 * 12 = F - 4

36 = F - 4

Adding 4 to both sides of the equation:

36 + 4 = F

F = 40

Therefore, the father is 40 years old.

Answer

The father is 40 years old.
