Question

Today is Varun's birthday. One year, from today he will be twice as old as he was $12$ years ago. How old is Varun today?

• A. $20$ years
• B. $22$ years
• C. $25$ years
• D. $27$ years

Answer 1

The correct option is C $25$ years

Let Varan's age today $=x$ years.
Then, Varan's age after $1$ year $=(x+1)$ years.
Therefore $x+1=2(x-12)\iff x+1=2x-24\iff x=25$.
