Solving the Mystery of the Age Difference: A Fun Mathematical Puzzle

Mathematics can often be approached with a playful mindset. One such entertaining challenge involves calculating the age of a person's brother based on the difference in their ages. This puzzle not only tests one's arithmetic skills but also reminds us of the intriguing mathematical relationships in our lives. Let's dive into the details of a popular age difference puzzle and explore different methods to find the solution.

The Challenge: How Old Is My Brother?

Imagine you are 37 years old, and your brother is 22 years older than you when you were 7. You might wonder, what is your brother's age now? This classic puzzle requires us to understand and apply basic subtraction and addition. Here, we will explore a few approaches to solve this problem.

Approach 1: Direct Subtraction

When you were 7, your brother was 22 years old. Calculate the age difference: 22 - 7 15 years. Now, you are 37 years old. Add the age difference to your current age: 37 15 52.

Therefore, your brother is 52 years old.

Approach 2: Age Calculation for a Specific Year

When you were 11 years old, your brother was 19 years old. Calculate the age difference: 19 - 11 8 years. Now, you are 37 years old. Add the age difference to your current age: 37 8 45.

It appears there was a miscalculation. Let's re-evaluate: if your brother is 8 years older than you, then when you are 37, your brother will be 37 8 45 years old, not 55 as initially stated.

Approach 3: General Formula Application

The age difference remains constant over time. If you are x years old, and your brother is x 15 years old (where 15 is the age difference), then:

If you are 23 years old, subtract the age difference from your age to find your brother's age: 23 - 5 18 years old.

Using the same formula, if you are 37 years old, add the age difference to your age to find your brother's age: 37 15 52 years old.

Conclusion

As we can see, solving the age difference puzzle is not as complicated as it might seem at first glance. By understanding the basic concept of age difference and simply applying addition and subtraction, we can solve the problem accurately.

Remember, whether you are 7, 11, or 37, the age difference between you and your brother remains constant. So, regardless of your current age, if you know the age difference, you can always calculate the other's age with ease!
