The age of the father is twice the sum of the ages of his two children.After,20 years , his age will be equal to the sum of the ages of his children.Find the age of the father
Let the age of father be x years and the sum of ages of two children be y years.
According to the question
Then after 20 years the age of father will be (x + 20) years and the sum of ages of two children will by (y + 2 × 20) = (y + 40) years
also x + 20 = y + 40 ... (2)
putting the value of y from (1) in (2) we get
Hence the age of the father is 40 years.
