Solving the Age Riddle: When Your Brother Was Half Your Age

Age puzzles often provide a fascinating brain teaser, engaging our minds with logical reasoning. One such riddle that many people find intriguing is the question of determining your brother's current age based on a point in time when he was half yours.

Understanding the Problem

The core of this riddle lies in the assertion that when you were 10 years old, your brother was half your age. As the years passed and you neared your 30s, the question arises: How old is your brother now?

Initial Analysis

When you were 10, your brother's age was half of yours, meaning he was 5 years old. This simple observation is the cornerstone of solving the entire problem. Let's break it down further:

When you were 10, your brother was 5 years old (10 / 2 5). This indicates that your brother is 5 years younger than you.

Evaluating the Problem with Math

To find your brother's current age, we need to take into account the passage of time. Here are the steps:

You are currently 30 years old. Since your brother is 5 years younger, we subtract 5 from your current age: 30 - 5 25.

Thus, your brother is 25 years old.

Additional Contexts

Sometimes, people may encounter similar problems with different ages. Let's consider another example for thorough understanding:

Another Example: When You Were 12

When you were 12, your brother was half your age (12 / 2 6). Your brother is 6 years younger than you. Currently, if you are 30 years old, subtract 6: 30 - 6 24.

In this scenario, your brother is 24 years old.

Key Takeaways

Your brother's age can be calculated by subtracting 5 years from your current age. This method works for any age you start with, as long as you have a clear understanding that your brother being half your age means he is 5 years younger. Solving these types of age puzzles helps in improving logical thinking and maintaining mental agility.

Conclusion

So, to answer the original riddle: If you are 30 years old now and were 10 when your brother was half your age, he is 25 years old. This age calculation is not a fluke or a coincidental result; it arises from a consistent application of basic arithmetic principles.

Age puzzles like these are not only fun but also serve as a mental exercise, sharpening our problem-solving skills. They remind us of the joy of thinking and the satisfaction of finding the solution to a riddle.
