Comparing Quantities: Discounts and Interest

Discount is a reduction on the marked price, calculated as Discount = Marked Price – Sale Price. It can also be computed using the discount percentage. Overhead expenses, added to the buying price, contribute to the cost price. Sales Tax, charged by the government, is included in the selling price, often represented as MRP which encompasses VAT. Interest compounded annually is based on the previous year's amount, while half-yearly compounding involves two conversion periods within a year. Formulas for calculating amounts based on compounding are provided. Examples illustrate how to determine discounts and profit or loss percentages.
