Fill in the blanks in junior one. Speed solution Given that a, B, C, D, e and F are six mutually unequal integers, and ABCDEF = - 36, then a + B + C + D + e + F =?

Fill in the blanks in junior one. Speed solution Given that a, B, C, D, e and F are six mutually unequal integers, and ABCDEF = - 36, then a + B + C + D + e + F =?

-36 decomposition prime factor = 2 * 2 * 3 * 3, and if expressed as the product of six different numbers, it can only be - 1 * 1 * 2 * (- 2) * 3 * (- 3)
Their sum is 0

A store sells a commodity with a purchase price of 8 yuan at 10 yuan per piece, which can sell 200 pieces per day. Now it adopts the method of raising the selling price and reducing the purchase quantity to increase the profit. It is known that the daily sales volume of this commodity will decrease 10 pieces per day when the price increases by 0.5 yuan. If the commodity is to make a profit of 640 yuan per day, how much should the selling price be?

Suppose the price is x yuan, according to the equation, we get (X-8) (200-x − 100.5 × 10) = 640, and the solution is X1 = 12, X2 = 16. Because we increase the profit by increasing the selling price and reducing the purchase quantity, we should set the selling price of each piece at 16 yuan, so that the daily profit can be 640 yuan

If a store sells goods with a purchase price of 8 yuan at 10 yuan per piece, it can sell 200 pieces per day. Now, the method of raising the price and reducing the purchase price is adopted to increase the profit

When the selling price is set at 11 yuan, the daily sales volume is 180 pieces, and the daily profit is 640 yuan

The original price of a commodity is x yuan, which is increased by 10% and then reduced by 20%. The current price is a, and the original price is?

X = a (1-20%) / (1 + 10%). Suppose that the original price is 100, 10% increase is 110 yuan, and then 20% decrease is 110 * 0.8 = 88 yuan

(1) The price of a commodity is reduced by 5% and the price is 190 yuan. What is the original price of this commodity?
(2) The flour yield of wheat is 85%. How many tons of wheat is needed to grind 34 tons of flour?
(3) The bicycle factory produced 900 bicycles in September, 25% less than in October. How many bicycles were produced in October?

(1) The original price of a commodity is 190 yuan at a price of 5%. The original price of this commodity is 190 yuan (1-0.05) = 190 yuan (0.95) = 200 yuan. (2) the flour yield of wheat is 85%. How many tons of wheat is needed to grind 34 tons of flour? (3) the bicycle factory produces bicycles in September

The original price of a commodity is 10 yuan, which is reduced by 10%, and then increased by 10%. How much is the current price?

10x (1-10%) x (1 + 10%) = 9.9 yuan

The original price of a commodity is 96 yuan, and the price after the price reduction is 80 yuan. What is the price reduction of this commodity? If the price after the price reduction is 76 yuan, what is the price reduction?

Price reduction
（96-80）÷96=16÷96≈16.7%
Price reduction
（96-76）÷96=20÷96≈20.8%

The price of a commodity is 80 yuan, which is 20 yuan lower than that in the past______ %．

20 (80 + 20), = 20 (100), = 20%; a: reduced by 20%

Judgment: a commodity price reduction of 20%, then 25%, the current price is equal to the original price

Wrong
(1-20%)×(1-25%)=60%
If it is: a commodity price 20%, and then 25%, the current price and the original price
That's right
(1-20%)×(1+25%)=100%
