The average of 10 and 20 is?

The average of 10 and 20 is 15. Calculating the average, or mean, involves summing the given numbers and then dividing by the total count of those numbers. In this case, you add 10 and 20 together, which results in 30. Since there are two numbers, you then divide 30 by 2. This division yields 15, demonstrating that the average of these two values is indeed 15.

Understanding how to calculate the average is a fundamental skill that is often tested in competitive exams. The concept of average allows for the comparison of different sets of data by providing a central value that represents the group. In this example, the numbers 10 and 20 can be thought of as two data points, and their average gives insight into their collective value. This calculation is not only applicable in mathematics but also in various real-life scenarios such as finance, statistics, and data analysis.

In conclusion, mastering the calculation of averages is essential for success in many competitive exams. It is important to practice this skill regularly, as it can often appear in varied forms within different questions. By clearly understanding how to derive the average, candidates can improve their problem-solving abilities and enhance their performance in quantitative sections of exams.
