Suppose store a sells x items, then store B sells 2x items. According to the meaning of the question, we get 200 × 20% · 2x-200 × 30% · x = 8000, and we get x = 400. Answer: if store a sells 400 items, then store B sells 800 items

Suppose store a sells x items, then store B sells 2x items. According to the meaning of the question, we get 200 × 20% · 2x-200 × 30% · x = 8000, and we get x = 400. Answer: if store a sells 400 items, then store B sells 800 items

Store a and store B buy the same kind of goods at the same price of 100 yuan. Store a sells the same goods at a 30% profit increase, and store B sells the same goods at a 20% profit increase. As a result, the number of goods sold by store B is twice that of store a, and the total profit is 4000 yuan more than that of store A. how many goods do store a and store B sell!

Suppose store a sells x items, then store B sells 2x items. According to the meaning of the title, the profit of a item sold by store a is 30 yuan, while that of store B is 20 yuan
20*2x-30*x=4000
So 10x = 4000
There are x = 400; 2x = 800
Shop a sold 400 items, shop B sold 800 items

The two stores buy the same commodity for 100 yuan
Store a and store B buy the same kind of goods at the same price of 100 yuan. Store a sells the same goods at a 30% profit increase, and store B sells the same goods at a 20% profit increase. As a result, the number of goods sold by store B is twice that of store a, and the total profit is 4000 yuan more than that of store A. how many goods are sold by store a and store B?

The selling price of a is 130 yuan, and that of B is 120 yuan. Suppose that the sales volume of a is x, then the sales volume of B is 2x
30x+4000=2*20x=40x
The solution is x = 400
So a sales volume of 400, B 800
