Question

A man is 42 years old and his son is 12 years old in how many years will the age of the son of the age of the son be half the age of the man at that time

Answer 1

Let the years after which the son's age becomes the half of the father's, be x

So, after x years, age of father = 42 + x

After x years, the age of the son would be 12 + x

Now, given that after x years, the age of son would be half, that is 1/2 of the father's age.


$= > \frac{1}{2} (42 + x) = 12 + x$

$= > \frac{42}{2} + \frac{x}{2} = 12 + x \\ \\ = > 21 + \frac{x}{2} = 12 + x \\ \\ = > 21 - 12 = x - \frac{x}{2} \\ \\ = > 9 = \frac{x}{2} \\ \\ = > x = 9 \times 2 \\ = > x = 18$


Hence, after 18 years, the age of son would become the half of the age of father.

Answer :- 18



» Verification «

So after 18 years, age of son = 12 + 18

= 30

After 18 years, age of father = 42 + 18

= 60

Now, since 30 = half of 60, so the answer is correct.
