When a store sells two items at the same time, it gets 120 yuan each. One of them earns 20% and the other loses 20%. Is it a profit or a loss to sell two items at the same time?

120 △ 1.2, = 100 (yuan); 120-100 = 20 (yuan); 120 △ 1-20%, = 120 △ 80%, = 150 (yuan), 150-120 = 30 (yuan), 20 ＜ 30, so selling two goods at the same time is a loss; answer: selling two goods at the same time is a loss

If a store sells two items at the same time, and each item gets 60 yuan, but one of them earns 20% and the other loses 20%, then the store sells the two items as ()
A. Don't earn or lose B. earn 5 yuan C. lose 5 yuan D. earn 10 yuan

The original price of the first commodity is: 60 △ 1.2, = 50 (yuan); the original price of the second commodity is: 60 △ 0.8, = 75 (yuan); the original price of two commodities is: 50 + 75 = 125 (yuan); the selling price of two commodities is: 60 × 2 = 120 (yuan); so the loss is: 125-120 = 5 (yuan); a: the store loses 5 yuan by selling these two commodities

If a store sells two items at the same time, and each item gets 60 yuan, but one of them earns 20% and the other loses 20%, then the store sells the two items as ()
A. Don't earn or lose B. earn 5 yuan C. lose 5 yuan D. earn 10 yuan

The original price of the first commodity is 60 ^ (1 + 20%), = 60 ^ 1.2, = 50 (yuan); the original price of the second commodity is 60 ^ (1-20%), = 60 ^ 0.8, = 75 (yuan); the original price of two commodities is 50 + 75 = 125 (yuan); the sales price of two commodities is 60 × 2 = 120 (yuan); so the loss is 125-120 = 5 (yuan)

When a store sells two items at the same time, each item gets 30 yuan. One of the items makes a profit of 20% and the other loses 20%. Is the store making a profit or losing money when it sells these two items? How much is it?

30 (1 + 20%) + 30 (1-20%) - (30 + 30) = 30 / 1.2 + 30 / 0.8-60, = 25 + 37.5-60, = 62.5-60, = 2.5 (yuan); a: the store loses 2.5 yuan in selling these two goods

(a store sells two items at the same time, each of which costs 60 yuan. One of the items earns 20% and the other loses 20%. Ask the store if it earns 20% by selling two items
Or loss

The cost of one piece is 60 / (1 + 20%) = 50 yuan
One is 60 / (1-20%) = 75 yuan
The loss is 75-60 = 15 yuan
Earn 60-50 = 10 yuan
Finally lost 15-10 = 5 yuan

A store sells two products at 120 yuan. It is known that one of them earns 1 / 5 yuan and the other loses 1 / 5 yuan. Then, does the product lose or gain
How many yuan do you lose? How many yuan do you earn?

One of them earns 1 / 5 of the purchase price: 120 (1 + 1 / 5) = 100 (yuan)
The purchase price of the other one with a loss of 1 / 5: 120 (1-1 / 5) = 150 (yuan)
Total purchase price of two pieces: 100 + 150 = 250 yuan
Total selling price of two pieces: 120 * 2 = 240 yuan
Loss: 250-240 = 10 yuan

When a store sells two goods at the same time, they are both 120 yuan. It is known that one of the goods makes 20% and the other loses 20%, so does the store make or lose? How many yuan do it make or lose? (I am a primary school student, don't write too complicated

It's not even

The price of a commodity is 120 yuan. If you reduce the price by 15%, you can make 20 yuan. If you make 8 yuan, what percentage of the price will be reduced?

Sixth grade percentage problem
Original price = 120 * (1-15%) - 20
=120*17/20-20
=102-20
=82
To earn 8 yuan, the price is 82 + 8 = 90
Price reduction; (120-90) △ 120 * 100%
=1/4*100%
=25%

The price of a commodity is 120 yuan. If you can reduce the price by 15%, you can earn 20 yuan. If you can earn 8 yuan, how much should you reduce the price?

120*15=18 20-8+18=30 30/120=25%

The original price of a commodity is 45 yuan, 10% off. How much has it been reduced

No more equations
The original price is 45 yuan, the price is 45 * 90% = 40.5 yuan
Reduced 45 - 40.5 = 4.5 yuan, that is a discount of the original price
It can also be directly calculated as 45 * (1-90%) = 45 * 10% = 4.5 yuan
Over, please criticize and correct
