Option 2 : 15 years

**Given:**

Difference between the ages of Aditya and his mother = 20 years

Age of his mother after 5 years = Twice of Aditya's age after 5 years

**Calculation:**

Let the age of Aditya be x years

Age of mother = (x + 20) years

Age of Aditya after 5 years = (x + 5) years

Age of his mother after 5 years = (x + 20 + 5) years

According to the question,

(x + 25) = 2 × (x + 5)

⇒ x + 25 = 2x + 10

⇒ 15 = x

**∴ The present age of Aditya is 15 years**
