Answer 1

Answer:

40 years

Step-by-step explanation:

Let the present age (in year) of father and his two children be x, y and z yr, respectively.

Now by given condition, x=2(y+z) …(i)

and after 20 yr, (x + 20) = (y + 20) + (z + 20)

⇒ y+z +40 = x +20

⇒ y + z = x – 20

On putting the value of (y + z) in Eq. (i) and get the present age of father

x =2(x -20) x

= 2x – 40 = 40

Hence, the father’s age is 40 yr.
