Question

A father is three times as old as his son. After twelve years his age will be twice as the age of his son. Find their present ages in years

• A. $12,36$
• B. $24,36$
• C. $36,16$
• D. None of these

Answer 1

The correct option is A $12,36$

Let, age of son $=$ $x$ years.
$\therefore$ age of father $=3x$ years.
According to the question, $2(x+12)=3x+12$
$\Rightarrow x=12$
$\therefore$ Son's age $=$ $12$ years
Father's age $=36$ years.
