Mathematical oddities
1. What is better than God and what is more evil than Satan? If you eat this thing, you will die. Please solve it mathematically. According to the meaning of the question, let God = +∞, Satan = -∞, and find X: X > +∞\ x & lt; -∞ So x ∈ φ So x=nothing 2. In order to gain the support of the poor and gain a good reputation of "charity", King Pumbaa decided to give each man 1 USD and each woman $40 (1 equal to 100). In order not to let him spend too much, your majesty calculated. Decided to land his helicopter in a poor mountain village at noon 12, because he knew very well that at that moment, 60% of the men in the village were out hunting, and there were 3085 adults in the village, ignoring the children, and there were more women than men. How much will this "careful" king send? How many men and women are there in the mountain village? There is no explanation in the question and the conditions are not complete. Can this problem be done? Suppose there are 1000 men in the village, so because 60% of the men are hunting, the king can only meet 400 people, plus 2085 women who look after the house, so the money the king should give should be1× 400+0.4 × 2085 = 400+834 =1. Just 500× (1-0.6) = 200 (person), and his expenditure should be1× 200+0.4× 2585 =1234 (USD). Suppose there are no men in this village, and the king meets all the women, and his charity expenditure is still 60. The three answers are exactly the same! I heard that this question was written by a famous math educator. American children like to do such tough open-ended questions. This is really a strange question! Let's try to use algebra to reveal the strangeness of this problem. Suppose there are X men in the village, then there are (3085-x) women, and the amount of money given by the king is: (1-0.6) x+0.4 (3085-x) = 0.4x+1234-0.4x =
