Answer 2

Answer:

Let my age be x years and my son’s age be y years.

Then at present, x=3y --- (1)

Five years later,

My age will be (x+5) and my son’s age will be (y+5) years.

From the statement given in question for 5 years later, we have

⇒(x+5)=(2+1/2)(y+5)

⇒(x+5)=(5/2)(y+5)

⇒2x+10=5y+25

⇒2x−5y−15=0 ---- (2)

Putting the value of x from equation (1) into equation (2), we get

⇒2(3y)−5y−15=0

⇒y=15

From equation (1)

x=3yx=3×15x=45

Hence, my present age is 45 years and my son’s present age is 15 years.
