Arithmetic and number systems are fundamental concepts in mathematics. They provide a foundation for solving various mathematical problems and have practical applications in our everyday lives. In CBSE Class 10 mathematics, you can expect questions that involve the applications of arithmetic and number systems in different contexts. These questions aim to test your understanding of these concepts and their real-world applications.


Arithmetic plays a crucial role in various practical situations. Some important applications of arithmetic in Class 10 mathematics include:

1. Money transactions: Arithmetic is used to calculate the total amount, discounts, taxes, and change in money transactions. You may encounter questions related to calculating the final price after applying discounts or finding the amount of change to be given.

2. Time and distance: Arithmetic is applied to solve problems related to time and distance. Questions may involve calculating the average speed, finding the time taken to cover a given distance, or determining the distance covered in a specific time period.

3. Measurement conversions: Arithmetic is used to convert measurements from one unit to another. Questions may require converting units of length, weight, time, or volume.

4. Percentages: Arithmetic is used to solve problems involving percentages. Questions may include calculating percentage increase or decrease, finding the percentage of a given quantity, or solving problems related to profit and loss.


Number systems are essential for representing and manipulating numerical information. Some applications of number systems in Class 10 mathematics include:

1. Binary system: The binary number system is used in computer science and digital electronics. Questions may involve converting decimal numbers to binary form or vice versa.

2. Real-life counting: Number systems are used for counting and keeping track of quantities in various real-life situations. Questions may require counting objects, determining the number of combinations or permutations, or solving problems related to probability.

3. Geometry: Number systems are applied in geometry to represent coordinates, lengths, areas, and volumes. Questions may involve finding the coordinates of points, calculating distances between points, or determining the areas and volumes of geometric figures.

4. Data analysis and statistics: Number systems are used to analyze and interpret data in statistics. Questions may involve calculating measures of central tendency, such as mean, median, and mode, or solving problems related to probability and data interpretation.


In CBSE Class 10 mathematics, you can expect questions that require applying arithmetic and number systems in various real-life contexts. These questions aim to test your understanding of these concepts and their practical applications. By practicing and understanding these applications, you will develop a strong foundation in arithmetic and number systems, which will be useful in solving mathematical problems and in practical situations throughout your life.
