The internet is a never-ending source of entertainment, offering everything from hilarious memes to fascinating facts shared by influencers and vloggers. But recently, a particular type of content has been gaining attention—brain teasers. These puzzles challenge your critical thinking skills and test your ability to apply logic and reasoning quickly. One such brain teaser has been making waves on social media, leaving many scratching their heads.

The brain teaser in question seems straightforward but is tricky enough to make you think twice. Here’s how it goes:

“When I was two, my sister was twice my age. Now I’m 40, how old is my sister?”

At first glance, this question might seem like a simple arithmetic problem, but it has sparked a flurry of responses and debates online. People have been sharing their calculations and interpretations, often arriving at different answers.

Why Is This Puzzle So Tricky?
The confusion surrounding this puzzle stems from overthinking. Many people get caught up in trying to apply complex calculations, assuming there’s a hidden trick or intricate formula needed to solve it. However, the key to this puzzle lies in its simplicity.

Let’s break it down to understand where people might be going wrong and how you can solve it in seconds.

Understanding the Puzzle: A Simple Breakdown
The puzzle starts by telling us that when the narrator was 2 years old, their sister was twice their age. Simple math tells us that if the narrator was 2, their sister must have been 4 years old. This initial piece of information establishes the age difference between the two siblings.

The critical part to understand is that the sister was twice as old as the narrator when they were 2, meaning the sister is 2 years older. This age difference remains constant as both siblings grow older.

Now, fast forward to the present day, where the narrator is 40 years old. Since the sister is 2 years older, she would be 42 years old. That’s it—no complicated math or tricks required!
