Practical Examples
Example 1: Finding 20% of a Price
If a laptop costs 80,000:
20% = 80,000 × 0.20 = 16,000
So, 20% of 80,000 is 16,000.
Example 2: Discount Calculation
If a shirt costs 2,000 and there is a 20% discount:
Discount = 2,000 × 0.20 = 400
Final Price = 2,000 − 400 = 1,600
Example 3: Adding 20% Tax
If a service costs 5,000:
Tax = 5,000 × 0.20 = 1,000
Final Cost = 6,000
