Let’s take a closer look at the puzzle to see where people might be going wrong and how you can solve it in seconds.

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 sets the stage for the age difference between the two siblings.

The critical piece of information here is that the sister was twice as old as the narrator when they were 2. This means the sister is 2 years older, and this age difference remains constant as both siblings age.

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

The trickiness of this puzzle lies in its wording, which can make people overthink the situation. The mention of “twice my age” when they were 2 can lead people to believe that some complex calculation is required, rather than recognizing that the age difference is a simple constant.

This brain teaser has garnered significant attention on social media, particularly on the X handle of Cocomellon, where it racked up over 200,000 views along with countless likes, retweets, and comments. The comments section has been buzzing with a variety of answers, ranging from correct solutions to more humorous interpretations.

Some users confidently shared their math, while others admitted to the challenge of figuring it out:

“42 na, unless she’s also aging twice as fast then she’d be 80 now.”
“The age difference between the two siblings is 4 – 2 = 2 years. Therefore, the person is now 2 + 40 = 42 years old. Their sister would be 4 + 40 = 44 years old.”

Others simply enjoyed the humor in the situation:

“No stress my brain abeg.”
“I swear I’m not stressing my brain.”
“Brain teaser…. Me wey never chop.”

The correct answer here is simply 42 years old. The puzzle is a classic example of how straightforward thinking can sometimes be the best approach. By keeping it simple and not complicating the problem, the answer becomes immediately clear.
