** 1. Table tennis game **
1. ** Title *
- Snowy kept asking Mingming to play table tennis with her. He had thought of a clever plan, saying that there was a yellow and a white ping-pong ball in the bag. He would play with Snowy if he got the yellow one, and Snowy would give up and not disturb him if she got the white one. But Snowy saw that there were two white ping-pong balls in the bag.
2. ** Answer **
- Snowy could take the ball out and hide it, then let Mingming see that the remaining balls in the bag were white, and infer that she was holding a "yellow" ball (because according to the rules, there were only one yellow and one white). In this way, she could ask Mingming to play table tennis with her.

** 3. The question of who has the money **
1. ** Title *
- In the year of famine, his father asked his five sons for help. He didn't know which of his sons was rich, but he knew that the brothers knew each other. The rich told lies, and the poor told the truth. "Of my four brothers, only one is rich," said the eldest. "Two of my four brothers have no money," said Second Brother. "Some of us brothers have no money," said Third Brother. "Big Brother and Second Brother are both rich," said Fourth Brother. "No. 3 is rich, and Boss has admitted that he doesn't have any money," said Old Fifth.
2. ** Answer **
- Third Brother said,"Some of us brothers are poor." It must be the truth. That's why No. 3 doesn't have money. Because the rich told lies, and the poor told the truth. The eldest brother said that only one brother was rich, so the eldest brother was rich; the fourth brother said that the eldest brother and the second brother were rich, so the fourth brother was rich; the fifth brother said that the third brother was rich, so the fifth brother was rich; the second brother said that two brothers were poor, so the second brother was poor. In short, the eldest, fourth, and fifth brothers were rich, while the second and third brothers were poor.
** 4. Inferring the time of the crime **
1. ** Title *
- Someone was killed at night. Four people provided the time of the crime. One person's watch was 5 minutes slower than the accurate time, one was 20 minutes faster, one was 3 minutes faster, and one was 12 minutes slower. They said the time was 12:08, 11:40, 12:15, and 11:53 respectively.
2. ** Answer **
- Let the accurate time be x, and solve the equation according to the relationship between the four people's watches and the accurate time. If the first person's watch was 20 minutes fast, the accurate time would be 11:48; if the grandpa's watch was 12 minutes slow, the accurate time would be 11:52; if the shop owner's watch was 3 minutes fast, the accurate time would be 12:12; if the lady's watch was 5 minutes slow, the accurate time would be 11:58. After analysis and comparison, the accurate time of the crime should be 11:52 (the old man's watch was 12 minutes slow).
** 5. Customer ordering problem **
1. ** Title *
- The waiter was going to serve breakfast for the 51 guests. The food included egg fried rice, steamed buns, and youtiao. There were two more customers who wanted Egg Fried Rice and steamed buns than those who only wanted steamed buns. There were two times more customers who only wanted steamed buns than those who only wanted youtiao. 25 customers didn't want youtiao, 18 customers didn't want Egg Fried Rice, 13 customers didn't want steamed buns, and 6 customers wanted youtiao and steamed buns instead of Egg Fried Rice. Ask for the number of customers.
2. ** Answer **
- If the number of customers who only wanted youtiao was x, then the number of customers who only wanted steamed buns was 2x, and the number of customers who wanted Egg Fried Rice and steamed buns was 2x + 2. According to the relationship between the number of guests, the equation was listed and solved. According to the calculation, there were 7 customers who only wanted youtiao, 14 customers who only wanted steamed buns, 8 customers who only wanted Egg Fried Rice, 16 customers who wanted two types of breakfast, and 6 customers who wanted all three types of breakfast.
** 6. Age Lies **
1. ** Title *
- There were four women, 41, 42, 43, and 44 years old. Two of them were discussing the issue of age, saying that the words of people older than them were all lies, and that the words of people younger than them were all true. "B is 43 years old," replied A. "A is not 41," said C.
2. ** Answer **
- Assuming that A is 41 years old, then C is telling the truth, and C is older than 41 years old; A said that B is 43 years old is false, so B is older than 41 years old and B is not 43 years old. Assuming that C was 44 years old, then A saying that B was 43 years old was false, and B was 44 years old. It was a contradiction. Assuming that C is 43 years old, because A said that B is 43 years old is false, B is 44 years old, A is 41 years old, and the condition is satisfied. Therefore, A was 41 years old, B was 44 years old, C was 43 years old, and the rest were 42 years old.

Each word represented a different number from 0 to 9, and the same word represented the same number. The "head" word was used as the entry point to solve the problem.
2. ** Answer **
- By analyzing and trying out combinations of numbers. For example, starting from the multiplication relationship of numbers, the specific answer needed to go through a complicated digital reasoning process. The complete calculation process was not listed in detail here, but the idea was to deduce step by step according to the mathematical operation rules and the characteristics of the numbers.
** 8. Water content of mushrooms **
1. ** Title *
- There are 1000kg of mushrooms, the water content is 99%, the water content is 98%, ask for the amount of water.
2. ** Answer **
- When the water content of 1000kg of mushrooms is 99%, the water weight is 990kg, and the solid mushrooms are 10kg. When the water content was reduced to 98%, the solid mushrooms accounted for 2%. Dividing 10 by 2%, the weight of the mushrooms was 500kg, so 500kg of water was dried.
** 9. Date Problem **
1. ** Title *
- If only yesterday was tomorrow, then today would be Friday. What day is it today?
2. ** Answer **
- Let the real day be a, and the difference between the real day and the imaginary day (Friday) be b. According to the meaning of the question,"today's hypothesis"=a + b. Since today is Friday, 5=a + b. If the real yesterday was taken as the imaginary tomorrow, then a - 1+2=a + 1 = 5, the solution was a = 4, which meant that today was Thursday. If the real tomorrow was taken as the imaginary yesterday, then a+1 - 2=a - 1 = 5, the solution was a = 6, which meant that today was Saturday. So in fact, today might be Thursday or Saturday.

Chen Yuanrong Blue RiverChen Yuanrong was the founder of Blue River Milk. In the last five years (2017 - 2022), under his leadership, Blue River Milk had created a new category of sheep milk powder through category innovation and brand start-up. They enjoyed policy dividends and gained market recognition. They also paid attention to brand image promotion and brand voice enhancement, achieving the top of the sheep milk powder category and having a brand image above the waist. However, Blue River also had problems at that time. For example, five years ago, the product category advantage was obvious, but the formula advantage wasn't enough. For this reason, from 2020 to 2022, Blue River took out 36 million Euros (264 million yuan) to upgrade the formula, upgrade the factory, and complete scientific verification.
He had a deep understanding of the baby powder industry. He believed that this was an industry that people just needed. It relied on the development of the population bonus. The competition was multi-dimensional, but in the end, it was the competition of product power. He believed that in the new five-year cycle of milk powder registered in the new national standard (starting in 2023), there were opportunities and challenges, such as policy dividends, product strength dividends, etc., which would be further released, and enterprises should grasp the dividends. He knew that industry problems were opportunities for the company, and trends were dividends for the company. Blue River wanted to do even better in the good areas and better in the bad areas, further expanding its advantages. For example, Blue River chose the most difficult way to register the new national standard. He used a comprehensive and high-quality formula to achieve a leap in upgrading. He also invested 36 million euros in formula research, nutrition upgrades, factory upgrades, and sheep milk innovation research. He also said that infant milk powder was not a luxury product. The market retail price was in the range of 200 - 360 yuan. The company should improve its product strength and brand strength to reduce costs and increase efficiency.
