Answer 2

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.
