age of the man at that time?​

Answer 1

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

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.

so simple....

please mark me as brainliest

Answer 2

Answer:

18 years

Step-by-step explanation:

42 - 12 = 30

So, when the man is 60 the son will be 30

Hence , in another 18 years the age of the son will be half the age of the man.
