​

Answer 1

Answer:

Ankit's Age = 40 years

Ankit's Son Age = 20years

Step-by-step explanation:

Let the present age of Ankit's son be x years

.Then Age of Ankit is 2x years .

Age of son 9 year ago=(x−9) years .

Age of Ankit after 4 years =(2x+4) years

(2x+4)=4(x−9)

⇒2x+4=4x−36

⇒2x−4x=−36−4⇒−2x=−40⇒x=20

Present age of Ankit=2x=40 years

.Present age of his son =20 years .
