`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. 25 years

B. 27 years

C. 20 years

D. 22 years

**Answer: A. 25 years**

**Solution:**

Let Varan’s age today = x years.

Then, Varan’s age after 1 year = (x + 1) years.

Therefore x + 1 = 2 (x – 12)

=> x + 1 = 2x – 24

**=> x = 25.**
