Answer 2

Answer:

Age of the father is 40 years now.

Step-by-step explanation:

Let the age of father be x

Let the sum of ages of the two children be y

  By data, x=2y ---------(1)

               x+20 = y+40

                 x - 20 = y

 (1) =>     x = 2(x-20)

               x= 2x - 40

               x = 40 yrs
