Answer 2

Answer:

Man's age = 40 yrs.

Son's age = 10 yrs

Step-by-step explanation:

Let the Man's age be x years and his son's age be y years

• It is given :

x = 4y -------------- (i)

After 20 years their ages will be

Man : x + 20

Son : y + 20

x + 20 = 2 ( y + 20 ) ----------------- (ii)

Substituting value of x in equation (ii) with 4y

=> 4y + 20 = 2y + 40

=> 4y - 2y = 40 - 20

=> 2y = 20

=> y = 10 years

Using in eq (i)

x = 4y

=> x = 40 years

Man's age = 40 yrs.

Son's age = 10 yrs
