Solving Chloe's Age Puzzle: A Seo-Friendly Guide
Mathematical puzzles are not only fun but also a great way to strengthen our problem-solving skills and understanding of algebra. In this article, we'll walk through a classic puzzle involving Chloe and her brother John. We'll solve the puzzle step by step and provide a detailed explanation so that you can understand the logic and algebra involved.
Introduction to the Puzzle
The puzzle goes like this: Chloe is 16 years old. Ten years ago, she was half of her brother John's age. How old is John now?
Understanding the Problem
To solve this puzzle, we need to translate the problem statement into a mathematical equation. Let's break it down:
Step 1: Determine Chloe's age 10 years ago.
Chloe's current age is 16. Ten years ago, she would have been:
16 - 10 6 years old
Step 2: Determine John's age 10 years ago.
According to the problem, Chloe was half of John's age 10 years ago. If Chloe was 6 years old, then John would have been:
6 x 2 12 years old
Solving for John's Current Age
To find John's current age, we add 10 years to his age 10 years ago:
12 10 22 years old
Conclusion
So, the answer to the puzzle is that John is currently 22 years old.
Alternative Methods to Solve the Puzzle
Let's solve the puzzle using algebra for a more general approach:
Let:
C Chloe's current age
J John's current age
Step 1: Define equations based on the given information.
From the problem:
C 16
C - 10 6 (Chloe's age 10 years ago)
J - 10 12 (John's age 10 years ago)
Step 2: Solve for John's current age.
J - 10 12
J 12 10
J 22
Detailed Reasoning
By following these steps, we can see that John is currently 22 years old. This puzzle is a great way to practice basic algebra and develop logical thinking skills.
