Question

4. A man is 42 years old and his son is 12 years
old. In how many years will the age of the son
be half the age of the man at that time?​

Answer 1

Answer:

Let us assume that it takes ‘x’ years for the son to be half of father’s age

So after ‘x’ years

Father’s age =42+x

Son’s age =12+x

Then as per given condition

Son’s age =1/2 of father’s age

That is 12+x=1/2(42+x)

2(12+x)=42+x

24+2x=42+x

2x-x=42–24

x=18

So there you go it takes 18years for the son to be half of his father’s age.

Explanation:

Question:

A man is 42 years old and his son is 12 years

old. In how many years will the age of the son be half the age of the man at that time?

To find:

In how many years will the age of the son be half the age of the man at that time?

Given:

Age of man = 42 years

Age of his son= 12 years

Solution:

Let the number of years= x.

Therefore the age of son would be 12+x

whereas the age of father would be 42+x.

A.T.Q.

2(12+x)=42+x

24+2x=42+x

2x−x=42−24

x=18

Hence, the number of years is 18.
