A batch of goods are priced at 50% of the profit. When they are sold, they are priced at 38% of the profit. After selling 40% of the apples A percentage problem, please see below A batch of goods are priced at 50% profit, and then they are priced at 38% profit when they are sold. After 40% of the apples are sold, the rest of the apples will be reduced. As a result, the total profit is 20% of the original profit. What is the price of the second reduction? Requirements: clear calculation step by step, complete formula. It's better to explain the meaning It's almost time for the graduation exam. It's hard to avoid being more careful

Apple 100kg, 10 yuan per kg
Original price: 10 × (1 + 50%) = 15 yuan
Current price: 10 × (1 + 38%) = 13.8 yuan
10 × (1 + 38%) × 100 × 40% = 55.2 yuan
100 + 50 × 20% = 110 yuan
110-55.2 = 54.8 yuan
54.8÷60×150≈60.9%
The special value method is used

During the exhibition period, a shopping mall sells a batch of goods at a lower price. If 10% of the price is subtracted from the sales, the profit will be 215 yuan. If 20% of the price is subtracted from the sales, the loss will be 125 yuan. How much is the purchase of the goods?

Set the price as X Yuan
Purchase price = 90x / 100-215
Purchase price = 80x / 100 + 125
Column equation: 90x / 100-215 = 80x / 100 + 125
The solution is: x = 3400
Purchase price = 90x / 100-215 = 2845

If a commodity is priced at 1000 yuan, it will get 60% profit. If the merchant sells at a discount, it will still get 20% profit. How much discount does the merchant sell?

Suppose that the purchase price of the commodity is X Yuan and the current price is y yuan,
(1-10%)y-x=180
x-(1-20%)y=240
The solution is x = 3600, y = 4200
So the purchase price is 3600 yuan

The price of a commodity is increased by 40% according to the cost price, and then it is sold at a 20% discount (80% of the price). The price is 240 yuan. Suppose the cost price of this commodity is x yuan. According to the meaning of the title, the correct equation listed below is ()
A. x•40%×80%=240B. x（1+40%）×80%=240C. 240×40%×80%=xD. x•40%=240×80%

Suppose that the cost price of this commodity is x yuan, and the price after the cost price is increased by 40% is x (1 + 40%), and the price after 20% discount is expressed as X (1 + 40%) × 80%. Because the price is 240 yuan, the equation is: X (1 + 40%) × 80% = 240

A commodity costs 40 yuan and sells for 55 yuan. What's the profit margin of this commodity?
Determinant results

(55-40)/40=37.5%

For a toy, it costs 40 yuan per piece, which is 20% lower than the original price. How much is the original price?

40 (1-20%) = 40 (1-20%) = 80% = 50 (yuan) a: it used to cost 50 yuan per piece

The price of commodity a includes 30% profit, and that of commodity B includes 25%. The total price of commodity a and commodity B is 480 yuan. The price of commodity a is 40 yuan higher than that of commodity B. how much is the cost of commodity a and commodity B?

Let a price X and B price y
X+y=480
x-y=40
X=260,Y=220
A cost 260 * 0.7 = 182
B cost 220 * 0.75 = 165

The price of commodity a contains 30% of the profit, while that of commodity B contains 40% of the profit. The total price of commodity a and commodity B is 470 yuan. The price of commodity a is 50 yuan more than that of commodity B. what are the costs of commodity a and commodity B?

Let a's unit price be x yuan. From the meaning of the question, we can get: x + (x-50) = 470, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 2x-50 = 470, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 2x = 520, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 260; 260-50 = 210 yuan

The price of commodity a includes 30% of the profit, and that of commodity B includes 40%. The sum of the two kinds of commodity prices is 470 yuan, and that of commodity a is 470 yuan
26 / 21 of B. cost of goods a and B

The price of Party B is 470 (1 + 26 / 21) = 210 yuan
A's price is 210x26 / 21 = 260 yuan
The cost of a is 260 (1 + 30%) = 200 yuan
The cost of B is 210 (1 + 40%) = 150 yuan

The price of commodity a contains 20% of the profit, and that of commodity B contains 40% of the profit. The price of commodity a and commodity B is 480 yuan in total. The price of commodity a is 60 yuan higher than that of commodity B, so the price of commodity B is higher than that of commodity a
How much is the cost of both goods?

If the price of B is x, then the purchase price of B is 0.6x, the price of a is (x + 60), the purchase price is 0.8 (x + 60) x + X + 60 = 480x = 210, so 0.6x = 210 * 0.6 = 126, 0.8 (x + 60) = 0.8 (210 + 60) = 216, that is, the cost of both goods is 216126. I'm glad to answer your questions
