Question

Twenty years ago, my age was $\left(\frac{1}{3}\right)$rd of what it is now. What is my present age?

• A. $66$ years
• B. $30$ years
• C. $33$ years
• D. $36$ years

Answer 1

The correct option is B $30$ years

Let the present age be $x$ years

$20$ years ago, age will be $x-20$

As per the given condition, we have

$x-20=\frac{x}{3}$

$x-\frac{x}{3}=20$

$\frac{2x}{3}=20$

$x=30$ years

Therefore, present age is $30$ years.
