Answer 1

Given:

The ratio of present ages of father, mother, and son = 8:5:2

Present age of father = 48 years

Formula used:

Average age = Total age/Number of members

Calculation:

We can find the present ages of the mother and son by using the ratio:

Mother's age = (5/8) × Father's age = (5/8) * 48 = 30 years

Son's age = (2/8) × Father's age = (1/4) × 48 = 12 years

After 3 years, their ages will be:

Father's age = 48 + 3 = 51 years

Mother's age = 30 + 3 = 33 years

Son's age = 12 + 3 = 15 years

The total age of the family after 3 years will be:

Total age = 51 + 33 + 15 = 99

The average age of the family after 3 years will be:

Average age = Total age/Number of members

Average age = 99/3 = 33

Therefore, the average age of the family after 3 years will be 33 years.
