Welcome to the first live class dedicated to preparing for the CDS and AFCAT 2 2024 Exam. In this session, we’ll delve into the fundamental concept of percentage, a topic that forms the bedrock of many mathematical calculations. Throughout the class, we’ll explore the concept of percentage, related formulas, and practice questions to reinforce our understanding.
Understanding Percentage: A Core Mathematical Concept
Percentage is a way of expressing a proportion or a fraction of a whole in terms of parts per hundred. It is denoted by the symbol “%”. Understanding percentage is essential for a wide range of real-life applications, including finance, business, and everyday calculations.
Exploring Percentage Formulas
To effectively work with percentages, it’s crucial to understand the related formulas:
- Percentage Change: Percentage change measures the relative difference between two values. It is calculated using the formula: Percentage Change = (New Value – Old Value) / Old Value * 100%
- Percentage Increase/Decrease: Percentage increase or decrease measures the change in value relative to the original value. It is calculated using the formula: Percentage Increase/Decrease = (Change in Value / Original Value) * 100%
Conclusion
In this class, we’ve explored the fundamental concept of percentage, along with related formulas and practice questions. Mastering percentage is essential not only for the CDS 1 2024 and AFCAT 2 2024 Exam but also for everyday mathematical calculations. Keep practicing, stay focused, and approach the exam with confidence!
