Let the present age of Sasi is x years.
The present age of Jeevan = (x – 3) years
Sum of their present ages = 19
⇒x + x – 3 = 19
⇒ 2x – 3 = 19
⇒ 2x – 3 + 3 = 19 + 3 (Add 3 on both sides)
⇒ 2x = 22
⇒ 2x/2 = 22/2 (Divide by 2 on both sides)
⇒ x = 11 years
∴ Present age of Sasi x = 11 years
Present age of Jeevan = x – 3
= 11 – 3 = 8 years
