Question

Man is 56 yrs old and son is 24 yrs old. In how many yrs, the father will be twice as old as his son at that time

Answer 1

Answer:

Step-by-step explanation:

present age of man = 56 years

present age of son = 24 years

let after x years the age of man will be twice as old as his son

after x years

age of man = (56+x) years

age of his son = (24+x) years

by condition:

age of man = 2(age of his son)

          56+x = 2(24+x)

          56+x = 48+2x

          56-48 = 2x-x

                   x = 8

therefore after 8 years the father will be twice as old as his son
