Understanding the Family's Average Age 5 Years Ago
Five years ago, the average age of the family (father, mother, and son) was 35 years.
- This means the total age of the family five years ago = 35 years * 3 = 105 years.
Since this was five years ago, we need to determine the total current age of the family:
- Current total age = 105 years + (5 years * 3) = 105 + 15 = 120 years.
Calculating the Average Age of Parents 3 Years Ago
Three years ago, the average age of the father and mother was 46 years.
- Thus, the total age of the parents three years ago = 46 years * 2 = 92 years.
To find their current total age:
- Current total age of parents = 92 years + (3 years * 2) = 92 + 6 = 98 years.
Finding the Present Age of the Son
Now, we can establish the present age of the son:
- Current total age of the family = Current total age of parents + Current age of son
- 120 years = 98 years + Current age of son
To find the son's current age:
- Current age of son = 120 years - 98 years = 22 years.
Thus, the present age of the son is 22 years, which corresponds to option 'D'.
