A color TV is 1900 yuan more expensive than a black and white TV, and the price of a color TV is 100 yuan less than five times that of a black and white TV
How much is each color TV set? Don't use the equation. I can't understand it. Use the column

Black and white TV = (1900 + 100) / (5-1) = 500 yuan
Color TV = 500 + 1900 = 2400 yuan

An electrical appliance store sold two TVs at the same time. The selling price was 4000 yuan. One of them earned 20% and the other lost 20%. Is it a profit or a loss?

Earned 20%, cost is 4000 / (1 + 20%) = 3333.33 yuan, profit is 4000-3333.33 = 666.67 yuan
Another lost 20%, cost 4000 / (1 - 20%) = 5000 yuan, loss 5000 - 4000 = 1000 yuan
The shopping mall lost 1000-666.67 = 333.33 yuan

The store returns a batch of notebooks and sets the price at 20% of the profit. When 60% of the notebooks are sold according to the price, in order to sell them as soon as possible, the rest will be sold at a discount. How much discount is the lowest to make a profit without losing money?

If the purchase price is 1, then: the original price is 1 × (1 + 20%) = 1.2; the result is 1.2 × 60% = 0.72; the remaining 1.2-0.72 = 0.48; the actual income is 1-0.72 = 0.280.28 △ 0.48 = 58% ≈ 60% = 60% = 60% discount; a: the lowest discount is 60% to sell, so as not to lose money and make a small profit

There is a kind of color TV set. Now the price of each set is 2895 yuan, which is 25% cheaper than the original price. How much is the original price?

2875/(1-25%)=3860

There is a kind of color TV set. Now the price of each set is 2895 yuan, which is 25% cheaper than the original price. How much cheaper is it now

2895÷（1－25％）－2895＝965

The current price of the color TV set sold by Tiantian Electric Appliance Co., Ltd. is 1260 yuan per set, 19 yuan lower than the original price?

1260 ÷ (1-19) = 1260 △ 89 = 1417.5 yuan a: the original price of each color TV is 1417.5 yuan
