ANSWER

Let x and y be the present age of mother and her daughter.

Therefore,

x+y=50

⇒x=50−y.....(1)

After 20 years, mother's age will be twice her daughter's age at the time.

x+20=2(y+20)

⇒x−2y=20.....(2)

From equation (1)&(2), we have

50−y−2y=20

3y=30

⇒y=10

Substituting the value of y in equation (1), we get

x=50−10=40

Hence the present age of mother and his son is 40 and 10 years respectively.
