Introduction

In mathematics, numbers play a vital role in solving various problems and equations. When we come across a problem that involves numbers, we need to understand the properties and relationships between them. In this article, we will explore the concept of even numbers and find the even number less than 10+20.

What is an Even Number?

An even number is a whole number that is divisible by 2 without leaving a remainder. For example, 2, 4, 6, 8, and 10 are all even numbers. Even numbers can be positive or negative, and they can be expressed in the form 2n, where n is an integer.

Understanding the Problem

The problem states that we need to find the even number less than 10+20. To solve this problem, we first need to calculate the sum of 10 and 20. The sum of 10 and 20 is 30. Now, we need to find the even number less than 30.

Finding the Even Number Less Than 30

To find the even number less than 30, we can start by listing the even numbers less than 30. The even numbers less than 30 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30. However, we need to find the even number less than 30, not equal to 30.

The Correct Answer

The correct answer is the even number that is less than 30 but not equal to 30. In this case, the correct answer is 28. 28 is an even number that is less than 30, and it satisfies the given condition.

Conclusion

In conclusion, the even number less than 10+20 is 28. We started by understanding the concept of even numbers and then applied it to the given problem. By listing the even numbers less than 30 and selecting the correct answer, we were able to find the solution to the problem.
