Question

Twenty years from now, Aditya's age will be three times his age today. What is his current age?

• A. 5 years
• B. 10 years
• C. 20 years
• D. 30 years

Answer 1

The correct option is B 10 years

Let, Aditya's current age be $x$
Twenty years from now, Aditya's age will be $x+20$.
Given, twenty years from now, Aditya's age will be three times his age today, which is $3x$.

⇒ $3x=x+20$
⇒ $2x=20$
⇒ $x=10$ years

Therefore, Aditya's current age is 10 years.
