Verified Answer
A father tells his son, "I was of your present age when you were born"...
Let the father's age be x and the son's age be y.
Then, x - y = y or x = 2y,
Now, x = 36. So, 2y = 36 or y = 18.
Therefore Son's present age = 18 years.
So, son's age 5 years ago = 13 years.

A father tells his son, "I was of your present age when you were born"...
The given information:
- The father is currently 36 years old.
- The father says that he was of the same age as the son when the son was born.

Analysis:
Let's assume the son's current age is x. According to the given information, the father's age at the time of the son's birth was also x. We can form the equation: father's age when the son was born = son's current age.

Solution:
To find the son's age five years ago, we need to subtract 5 from the son's current age. Let's solve this step by step.

1. Let's assume the son's current age is x.
2. According to the given information, the father's age when the son was born was also x.
3. Currently, the father is 36 years old.
4. So, the son's current age is x = 36.
5. To find the son's age five years ago, subtract 5 from the son's current age: x - 5 = 36 - 5 = 31.

Therefore, the son was 31 years old five years ago.

Conclusion:
The correct answer is option A) 13.
