Answer:
36
Step-by-step explanation:
Let present age of father and son be x and y respectively
then 5 years ago sum of then age is 20.
⇒(x−5) + (y−5)=20
x + y = 30 ⇒ y = 30 −x
After 2 years ; sum of age of father and son is
Let z = (x+3) + (y+3)
z = (x+3+30−x+3) from (1)
= 30 + 6
z = 36
So sum of their ages after 2 years = 50.
