8. The age of the father is 40 years while his son's age is 10 years. After how many years will the age of
the father be twice the son's age? ​

Answer 1

Answer:

After 20 years the age of the father would be twice that of the son

Step-by-step explanation:

the current age of the father and son = 40/10

let after x years the age of the father will be twice that of the son

so 40 + x / 10 + x = 2

then, 40 + x = 20 + 2x

therefore, x = 20

so after 20 years, the son will become of (20 + 10) 30years and the father will become (40 + 20) 60 years i.e., twice that of son
