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 ?Options20 years 25 years 27 years 22 years
Solution
Let's denote Varun's current age as X.
According to the problem, one year from today, Varun will be twice as old as he was 12 years ago.
This can be written as an equation: X + 1 = 2 * (X - 12)
Solving this equation will give us Varun's current age.
First, distribute the 2 on the right side of the equation: X + 1 = 2X - 24
Then, subtract X from both sides to get: 1 = X - 24
Finally, add 24 to both sides to solve for X: X = 25
So, Varun is 25 years old today.
