The original profit rate of a commodity is 47%. Now because the purchase price has increased by 5% and the selling price has not changed, the sales profit rate of this commodity has become.
3. A businessman deals in two commodities, A and B, and the profit rate of each commodity is 40%, and B is 60%. When the sales volume of commodity B is 50% more than that of commodity A, the businessman gets 50% of the total profit rate. When the sales volume of Class B goods is 50% less than that of Class A goods, the total profit rate obtained by this businessman is.
A shopping mall sells a batch of TV sets. /kloc-the gross profit of each TV set in October is 20% of the selling price (gross profit = selling price-buying price). In February, the mall lowered the price of each TV set by 65,438+00% (the purchase price remained unchanged). Results The sales volume of TV sets increased by 65,438+020% compared with 1 month, so the ratio of gross profit in February to gross profit in 1 month.
Analysis: For the ratio of February gross profit to 1 month gross profit, we need to calculate February gross profit and 1 month gross profit respectively, and gross profit = unit gross profit × sales volume. If the price of 1 month is x and the sales volume is y, according to the meaning of the question, we can use the algebraic expression containing x and y to represent the gross profit of February and the gross profit of 1 month, and then calculate their ratio.
Solution: If the selling price of 1 month is X and the sales volume is Y, then the buying price is X × (1-20%) = 80% X.
1 month gross profit is x× 20% x y = February selling price is x (1-10%) = 90% x.
The gross profit of each set is 90%x-80%x= 10%. The number of units sold in February is y× (1+120%) = 220% y.
So the gross profit in February is 10%x×220%y=22%xy.
5. Market research shows that the relationship between the sales rate () and the price multiple () of a commodity satisfies the relationship (). According to the relevant regulations, the price of goods should not exceed 2 times the purchase price. If a shopping mall wants to make a profit of 50% from the goods, then the price multiple of the goods should be _.
6. A beverage produced by a company is made of two raw materials according to a certain proportion, in which the raw material cost price is 15 yuan/kg, and the raw material cost price is 10 yuan/kg, and the profit rate per kg is 70% at the current price. Due to market competition and rising prices, raw materials increased by 20% and 65,438+00% respectively. Total cost increases after compilation 12%. In order to expand the market, the company plans to invest 25% of the total cost in advertising. If you want to keep the profit per kilogram unchanged, the profit rate of this drink at this time is.
7. "Energy saving and emission reduction, low-carbon economy" is the future development direction of China. A car manufacturer produces large, medium and small displacement cars. In general, small-displacement vehicles account for 30% of the total output. In order to actively respond to the call of the state and meet the consumer demand of the public, it is planned to increase the production of small-displacement vehicles. Due to the adjustment of its production structure, the output of large and medium-displacement vehicles is only 90% of the normal situation, but the total output is 7% higher than the original.
8. Company A sells three products, A, B and C. In last year's sales, the sales amount of high-tech product C accounted for 40% of the total sales amount. Due to the impact of the international financial crisis, the sales amount of products A and B will be reduced by 20% this year, so high-tech product C is the focus of this year's sales. If the total sales this year is the same as last year, the sales of high-tech product C should increase by%.
9. There are two kinds of drinks, A and B, which contain the same fruits and vegetables, but with different concentrations. A drink weighs 40kg, and B drink weighs 60kg. Now pour out a part of each beverage with the same weight, and then mix the poured part of each beverage with the rest of another beverage. If the mixed two drinks contain the same concentration of fruits and vegetables, then the same weight of each drink is _ _ _ _ _ _ _.
