Question

Mr. Vijay is 42 years old and his son is 14 years old. Determine the ratio of the father's age to that of son's age when the son was 12 years old.

• A. 28 : 12
• B. 10 : 3
• C. 12 : 40
• D. 3 : 10

Answer 1

The correct option is B 10 : 3

Given: Father's age = 42 years
Son's age = 14 years
Two years ago, his son was 12 years old and father was 42 - 2 = 40 years.
Now, two years ago, the ratio of father's age to son's age will be:
$\frac{40}{12}=\frac{10}{3}$
Therefore, the required ratio is 10 : 3.
