Question

. 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.
​

Answer 1

Answer: Age of father is 40 years.

Step-by-step explanation:

Let age of father be x.

Let sum of ages of his children be y.

ATQ,

x = 2y

Moreover, in 20 years father's age will be x while his children will advance 20 years each, so their sum will be y + 40. So,

x + 20 = y + 40

puttin x = 2y,

2y+20 = y+40

y=20

As x = 2y = 2(20)= 40.

So age of father is 40 years old
