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. 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.
