===> let the present age of John be 'x'

===> the present age of his father will be 10+2x

after 10 years,

===> age of John will be 10+x

===> age of his father will be 10+2x+10

using condition,

===> 20+2x = 2(10+x)

solve further you will get the answer

Answer 2

Answer:

Let the present ages of father and son be 2x + 10 and x years respectively.

By the given condition

(2x+10+10) = 2(x+10)

⇒2x+20=2x+40

Which is unsolvable
