Deduction refers to the number of points to be discounted on the basis of quotation. Deduction points are often used in commodity trading and trade price negotiation. For example, the deduction point of 65,438+00 is used to discount the existing price by 65,438+00%.

Note: 10% is 10%, which means 10% discount, so 10% discount means that the actual selling price is 90% of the original selling price.

Take the original price of goods as 100 yuan as an example, and give a 10% discount, that is, 100 * 90% = 90 yuan.

Calculation method:

1, original price × (discount10)

For example, the original price of 70 yuan is 30% off, that is, 70× (3 ÷ 10) = 2 1.

For example, 20% discount means: original price × 20% discount.

2. Original price × discount/10

For example, the original price of 40 yuan is 50% off, that is, 40×5/ 10 =20.

3. Original price ×0. discount

For example, the original price 100 yuan, 10% discount, that is:100× 0.1=10.
