**Karim's Family Ages: A Mathematical Puzzle**

Introduction

In this article, we will explore a mathematical problem involving the ages of Karim, his brother Azam, and their father. We will use algebraic expressions to represent their current ages and then calculate their ages after 5 years.

The Problem

Karim is x years old. His brother Azam is 5 years older than him, so Azam's age can be represented as x + 5. Their father is 3 times as old as Azam, so their father's age can be represented as 3(x + 5).

Representing Their Ages Algebraically

Let's represent their current ages using algebraic expressions:

Karim's age: x
Azam's age: x + 5
Father's age: 3(x + 5)

Calculating Their Ages After 5 Years

To calculate their ages after 5 years, we need to add 5 to each of their current ages.

Karim's age after 5 years: x + 5
Azam's age after 5 years: (x + 5) + 5 = x + 10
Father's age after 5 years: 3(x + 5) + 5 = 3x + 15 + 5 = 3x + 20

The Sum of Their Ages After 5 Years

To find the sum of their ages after 5 years, we need to add their individual ages together.

Sum of their ages after 5 years = (x + 5) + (x + 10) + (3x + 20) = 5x + 35

Solving for x

Since we are given that Karim is x years old, we can use this information to solve for x. However, we are not given any specific value for x. Therefore, we will leave the expression in terms of x.

Conclusion

In this article, we used algebraic expressions to represent the ages of Karim, Azam, and their father. We then calculated their ages after 5 years and found the sum of their ages after 5 years. The sum of their ages after 5 years is 5x + 35.

Example Use Case

Suppose we know that Karim is 20 years old. We can substitute this value into the expression for the sum of their ages after 5 years.

Sum of their ages after 5 years = 5x + 35 = 5(20) + 35 = 100 + 35 = 135

Therefore, the sum of their ages after 5 years is 135.

Real-World Applications

This problem can be applied to real-world scenarios where we need to calculate the ages of individuals or groups of people after a certain period of time. For example, in a family planning scenario, we may need to calculate the ages of children and their parents after a certain number of years.

Mathematical Concepts

This problem involves the following mathematical concepts:

Algebraic expressions
Addition
Substitution

Key Takeaways

Algebraic expressions can be used to represent the ages of individuals or groups of people.
Addition can be used to calculate the ages of individuals or groups of people after a certain period of time.
