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?

Answer 1

Age of son = 12 yrs Age of man = 42yrs Let the years after which the age of the son will be the half of age of the man be x. So, we have to prove = age of son/age of man =1/2 Now, 12+x/42+x = 1/2 By cross multiplication =24+2x = 42+x = 2x-x = 42-24 = x = 18 yrs answer  If it helps you then mark my answer as brainliest.   Thank You!
