Why Percentage Change Matters
Mastering percentage calculations is essential for:
- Financial Literacy: Understanding discounts, interest rates, and investments
- Data Interpretation: Analyzing trends in business, economics, and statistics
- Competitive Exams: Frequently tested in aptitude tests, bank exams, and government job tests
Percentage Change Example
Problem: A product's price increased by 20% and then decreased by 15%. What is the net percentage change?
Step 1: Let original price = ₹100
Step 2: After 20% increase: 100 + 20 = ₹120
Step 3: After 15% decrease: 120 - (15% of 120) = 120 - 18 = ₹102
Net change: 102 - 100 = 2% increase
Keep Practicing Percentage Problems
