Introduction
Mathematics is a fascinating subject that surrounds us in every aspect of life. It's a language that helps us understand the world around us, from the simplest calculations to the most complex theories. In this article, we'll delve into a simple yet intriguing math problem that involves a brother and sister, Anu and her brother. We'll explore how to solve this problem using basic arithmetic operations and mathematical concepts.
The Problem
Anu Gupta is 4 years younger than her brother. If Anu is 8 years old, how old is her brother?
Breaking Down the Problem
To solve this problem, we need to understand the relationship between Anu's age and her brother's age. We're given that Anu is 4 years younger than her brother, which means her brother is 4 years older than her. We're also given that Anu is 8 years old.
Step 1: Identify the Given Information
- Anu's age: 8 years
- Relationship between Anu's and her brother's age: Anu is 4 years younger than her brother
Step 2: Use the Relationship to Find the Brother's Age
Since Anu is 4 years younger than her brother, we can represent her brother's age as x. We know that Anu's age is 8, so we can set up the equation:
x - 4 = 8
Step 3: Solve the Equation
To solve for x, we need to isolate the variable. We can do this by adding 4 to both sides of the equation:
x - 4 + 4 = 8 + 4 x = 12
Conclusion
Therefore, Anu's brother is 12 years old.
Why This Problem Matters
This problem may seem simple, but it's an excellent example of how math is used in real-life scenarios. Understanding relationships between variables and using basic arithmetic operations are essential skills that are used in various fields, such as science, engineering, and finance.
