Answer:
let Jhon is x years old
so his father is 2x years
after 20 years Jhon will be (x+20)years and his father will be (2x+20)years
according to question,
(2x+20).2/3=x+20
=> 2(2x+20)=3(x+20)
=> 4x+40=3x+60
=> 4x-3x=60-40
=> x=20
so Jhon is now 20 years old and his father is now 2×20years=40 years old
