Step -1: Forming equations.

Let, present age of son = x

And, present age of father = 3x+3

3 years later, age of son = x+3

age of father = 3x+3+3=3x+6 ...(i)

According to the given condition, age of father = 10+2(x+3) ...(ii)

Step -2: Solving for x

From (i) and (ii)

∴3x+6=10+2(x+3)

⇒3x+6=10+2x+6

⇒3x−2x=10+6−6

⇒x=10

∴Present age of son = 10

and present age of father = 3x+3=3×10+3=33

Hence, son’s present age is 10 years and father’
