​

Answer 1

The age of the father today is 2 times the sum of the age of the children today. the age of the father 20 years from now is 60. the sum of the age of the children 20 years from now is 20 + 40 = 60. the age of the father 20 years from now is equal to the sum of the age of the children 20 years from now.

Answer 2

Answer:

sum of the ages of children be x+y

father age is twice the sum of children age

: father age = 2(x+y)

after 20 years from now. 2(x+y)+20=x+y+20. 2x+2y+20= x+y+20.
