Rizhao midterm exam questions
(1) What was the sales volume of household appliances of the pilot products in the same period in 2007?

(2) If the average selling price of household appliances is: each color TV 1.500 yuan, and each refrigerator is 2,000 yuan, which is 3/2 times the number of color TV sets, how many tens of thousands of color TV sets, refrigerators and mobile phones are sold respectively, and how many tens of thousands of government subsidies are calculated respectively?

Solution1:3.5 million units/(1+0.4) = 2.5 million units.

Option 2: The number of color TV sets sold is X; The sales volume of refrigerators is 1.5X, and that of mobile phones is (350-2.5X).

0.15x+0.2 *1.5x+0.08 * (350-2.5x) = 500,000 yuan.

0.45 times +28-0.2 times =50

0.25x=22

The number of color TV sets x = 880,000,

The number of refrigerators is 1.5x = 1.32 million.

The sales volume of mobile phones is (350-2.5x) = 1.3 million.

Government subsidized color TV sets = 880,000 sets * 0.15 *13% =1.71600 million yuan.

Government subsidized refrigerators = 1.32 million units * 0.2 *13% = 343.2 million yuan.

Government subsidized mobile phone = 654.38+0.3 million * 0.08 * 654.38+03% = 654.38+35.2 million yuan.
