1. Stating the problem: We need to complete the table by finding the missing values for marked price, selling price, and discount percentage using the given data. 2. Formula used: The discount percentage is calculated by $$\text{Discount %} = \frac{\text{Marked Price} - \text{Selling Price}}{\text{Marked Price}} \times 100$$ 3. Important rules: - Marked Price is the original price before discount. - Selling Price is the price after discount. - Discount % tells how much percent was reduced from the marked price. 4. First row is complete: Marked Price = 160, Selling Price = 24, Discount % = 15% (given). 5. Second row: Marked Price = 21.95, Selling Price = 16.95, Discount % is missing. Calculate discount %: $$\text{Discount %} = \frac{21.95 - 16.95}{21.95} \times 100 = \frac{5}{21.95} \times 100 \approx 22.79\%$$ 6. Third row: Selling Price = 449.95, Discount % = 10%, Marked Price is missing. Use formula rearranged to find Marked Price: $$\text{Selling Price} = \text{Marked Price} \times (1 - \frac{\text{Discount %}}{100})$$ $$449.95 = \text{Marked Price} \times (1 - 0.10) = \text{Marked Price} \times 0.90$$ $$\text{Marked Price} = \frac{449.95}{0.90} \approx 499.94$$ 7. Final completed table: - Row 1: Marked Price = 160, Selling Price = 24, Discount % = 15% - Row 2: Marked Price = 21.95, Selling Price = 16.95, Discount % = 22.79% - Row 3: Marked Price = 499.94, Selling Price = 449.95, Discount % = 10% This completes the missing values using the discount formula and basic algebra.
