In daily life and work, we often need to calculate percentages, such as discounts, tax rates, commissions, etc. Below we will detail how to calculate the result of a 100% deduction of 20% and ** its application in real life.
1. Calculation method
The calculation of 100% deduction of 20% is as follows:
First, we need to find out the value of 20%, i.e. 20% of 100 = 20.
Then, subtract 20 from the original value of 100, i.e. 100 - 20 = 80.
Therefore, 100 minus 20% results in 80.
Second, practical application
1.Discount calculation: When shopping, merchants often offer discount offers. For example, the original price of a product is 100 yuan, and after a 20% discount, the actual payment** is 100 * 80% = 80 yuan. The 20% discount here refers to the discount rate, which is 80% of the original price.
2.Tax rate calculation: When conducting financial transactions, we need to calculate taxes based on the tax rate. For example, if the VAT rate of a country is 20%, then for 100 yuan of goods, the VAT fee to be paid is 100 * 20% = 20 yuan.
3.Commission calculation: In the sales industry, salesmen usually get a certain percentage of commission based on sales. For example, if a salesman's commission ratio is 20%, then the commission he can get from selling 100 yuan of goods is 100 * 20% = 20 yuan.
3. Other calculation methods
In addition to the direct subtraction calculation, we can also use multiplication to calculate the result of 100 deducting 20%:
Multiply 100 by (1-20%), i.e. 100 * 1-20%) = 100 * 80% = 80.
This approach is useful when dealing with more complex percentage calculation problems, such as calculating compound interest rates, depreciation rates, and so on.
The calculation method of 100% deduction of 20% is relatively simple, just choose the appropriate calculation method according to the actual situation. In real life, we should learn to use these calculations to solve various percentage problems.
