The 29800 Olympic Stamp Set was a set of stamps that included all the countries (regions) participating in the 29th Olympic Games. There were four volumes in this set of stamps, and each volume had a different release date. The design of the stamps was exquisite. It was a collection of the first stamps issued by more than 120 participating countries for the Olympic Games. Each album contained the history of the ancient Olympic Games, the history of the modern Olympic Games, and the stamps of various countries. The information was provided by the International Olympic Committee and verified. This collection of stamps was a special stamp product jointly authorized by the International Olympic Committee and the Beijing Organizing Committee for the Olympic Games. It was limited to 30,000 sets worldwide. The price of the stamps was 29800 yuan. The current market price of the Stamp Encyclopedia was about 15,000 to 20,000 yuan. This set of stamps was a high-end stamp product, suitable for collectors.
Suppose Congcong collected x stamps and Xiaoxiao collected y stamps.
According to the conditions in the question, the following two equations can be listed:
x + y = 171 (171 stamps collected)
x = 4y (1/4 of Congcong's stamps is equal to 1/5 of Xiaoxiao's stamp collection)
Substituting x from the first equation into the second equation gives:
4y + y = 171
5y = 171
y = 342
Substituting y = 342 into the first equation gives:
x + 342 = 171
x = 1378
Therefore, Congcong collected 1378 stamps and Xiaoxiao collected 342 stamps.
In 2024, China Post would issue several sets of stamps. This set of stamps included two special stamps with a face value of 1.20 yuan and a small promissory note with a selling price of 16 yuan. In addition, there were special stamps of China's shipbuilding industry (II). This set of stamps included four stamps with a face value of 4.80 yuan. Other specific stamp distribution plans and topics had not been provided yet.
Suppose that Xiaoling's original number of stamps was x, and Xiaojun's original number of stamps was y.
According to the meaning of the question, after Xiao Ling gave Xiao Jun 8 stamps, the number of stamps between the two of them was the same. The following equation could be listed:
x + 8 = y
And because Xiaoling gave Xiaojun 8 stamps, the two of them had the same number of stamps, so the following equation could be listed:
x - 8 = y - 8
Adding 8 to x in the first equation gives:
x + 8 = x + 8 + 8
After the reduction, it was obtained:
2x = 16
Solve the equation:
x = 8
Substituting x = 8 into the first equation gives:
8 + 8 = y
Solve the equation:
y = 6
Therefore, Xiaoling's original number of stamps was 8, and Xiaojun's original number of stamps was 6.
Therefore, Xiaoling's original stamps were 8 - 6 = 2 more than Xiaojun's.
Ten Bamboo House stamps were stamps with the painting and calligraphy of Ten Bamboo House as the theme. These stamps were based on Hu Zhengyan's " Ten Bamboo Studio Painting and Calligraphy Manual " of the Ming Dynasty, which showcased the artistic style and techniques of the Ming Dynasty prints. The designs on the stamps included calligraphy, painting, engraving, and many other art forms. Each stamp was accompanied by an inscription and a poem. The Ten Bamboo House stamps had a certain reputation and collection value in the Chinese stamp collection industry.
Assuming Beibei has x stamps, Lele has x-18 stamps.
According to the meaning of the question, after Lele gave Beibei 146 stamps, the number of stamps that Lele had was x-18+146, which was x-17.
Therefore, we can get the equation:x-17 = x-18+146.
If the equation was simplified to 2x-34 = 146, then x = 69.
Therefore, Bei Bei had 69 stamps and Le Le had 69-18=51 stamps.
Therefore, Lele had 51-69=-18 stamps more than Beibei.
Xiaoling and Xiaojun were both collecting stamps. After Xiaoling gave Xiaojun eight stamps, they both had the same number of stamps. Xiaoling's original number of stamps remained unchanged. This was because the face value of the stamp multiplied by the number of stamps was equal to the total number of stamps. After Xiaoling gave Xiaojun 8 stamps, the total number of stamps was the same for both of them, so Xiaoling's original number of stamps remained unchanged.
