​

Answer 1

Answer:

Age of father is 40 years.

Step-by-step explanation:

Let the age of father be x years

Let the age of one of his children be y years and age of another children be z years

From given information

x=2(y+z)....(1)

After 20 years

(x+20)=(y+20)+(z+20)....(2)

Substituting value of (1) in (2),we get

2(y+z)+20=y+z+40

2y+2z-y-z=40-20

y+z=20....(3)

Substituting value of (3) in (1),we get

x=2*(20)

=>x=40

Age of father is 40 years.
