Key idea: Discount
A discount is a reduction off the **marked price** (MP), not the cost price. The selling price (SP) is what the customer actually pays.
**SP = MP − Discount**
**Discount % = (Discount / MP) × 100**
Example: shirt MP ₹800, discount 25%. Discount amount = 25% of 800 = 200. SP = 800 − 200 = 600.
Note: discount % is calculated on MP. Profit/loss % (Class 7) is on CP. Don't mix them up.
**SP = MP − Discount**
**Discount % = (Discount / MP) × 100**
Example: shirt MP ₹800, discount 25%. Discount amount = 25% of 800 = 200. SP = 800 − 200 = 600.
Note: discount % is calculated on MP. Profit/loss % (Class 7) is on CP. Don't mix them up.
