If a son is younger than his father by 25 years and the father was 45 years old, 4 years ago. What will be the total age of the father and son after 5 years ?

Options

A. 82 years
B. 88 years
C. 83 years
D. 78 years

Answer

To solve the problem step by step, we will determine the current ages of the father and son, and then calculate their total age after 5 years.

### Step 1: Determine the father's current age
From the problem, we know that the father was 45 years old 4 years ago. Therefore, we can calculate his current age as follows:

\[ \text{Father's current age} = 45 + 4 = 49 \text{ years} \]

### Step 2: Determine the son's current age
The problem states that the son is 25 years younger than his father. Therefore, we can calculate the son's current age as follows:

\[ \text{Son's current age} = \text{Father's current age} - 25 = 49 - 25 = 24 \text{ years} \]

### Step 3: Calculate the ages after 5 years
Now, we will find out how old both the father and the son will be after 5 years.

\[ \text{Father's age after 5 years} = 49 + 5 = 54 \text{ years} \]
\[ \text{Son's age after 5 years} = 24 + 5 = 29 \text{ years} \]

### Step 4: Calculate the total age after 5 years
Finally, we will calculate the total age of both the father and the son after 5 years.

\[ \text{Total age after 5 years} = \text{Father's age after 5 years} + \text{Son's age after 5 years} = 54 + 29 = 83 \text{ years} \]

### Final Answer
The total age of the father and son after 5 years will be **83 years**.
