Coincidentally, the sum of the numbers of each chicken farm is equal to 34. How many chickens are raised in this 10 chicken farm? 8. In the table below, what is the first number on the left of line 100? 54326789131211517 265438+._ _ _ _ _ _ _ _ _ _ _ _ Boys can walk three steps per second and girls can walk two steps per second. As a result, the boy walked 650 steps from one end of the escalator to the other. Replace all 2 in this five-digit odd number with 5, all 5 with 2, and keep the other numbers unchanged to get a new five-digit number. If half of the new five digits are 1, what are the original five digits? Answer 1. (1) The sum of A and B plus A is 220, and B plus B is 65438. Sum of two numbers B. According to the problem, 2A+2B = 220 (1) A+2B =170 (2) (1) formula +(2) gives 3 A +3 B =390. So, the sum of a and b is 390? = 130 (2) Xiao Ming misspelled the dividend 1 15 as 15 1. The quotient of the result is 3 larger than the correct result, but the remainder is exactly the same. Write this division formula. Because the quotient is increased by 3, the divisor can be obtained (65438). =36? = 12 Therefore, the division formula is: 1 15? 2 = 9 ... 7 2. (1) Fill in the appropriate numbers in the following () so that the average of the three numbers is 140. The average of (5), (8)8 and (3)27 is 140, so the sum of the three numbers is 65438+. =420 The third number should be 327 420-327=93. Obviously, the first number is 5 and the second number is 88. (2) Fill in the numbers 5, 20, 45, 80, 125, 180 according to the law. 245.20 = 5+1545 = 20+25 80 = 45+35125 = 80+45, so the next number should be: 125+55= 180 3. The step map of each layer is made of black and white. So what is the number of white squares on the 2000th floor? According to the observation chart, the number of white squares on each floor is equal to the number of floors minus 1, so there should be 1999 white squares on the 2000th floor. In a parking lot, 48 cars and motorcycles were parked, including 4 wheels for each car and 3 wheels for each motorcycle. = 192 So the number of motorcycles is (48? - 172)? 4- 1) =20 (vehicle) has 48-20=28 (vehicle) 5. Give 100 apples to 10 children, and the number of apples per child is different. The child who gets the most apples must get at least a few apples, and the number of apples of all people should be as close as possible, 65438+. 3... 10 apples, and the remaining apples are divided by 10 to get [100-(1+2+3+...+10)]? 0 =45? 0 = 4 ...5 So, if you add four apples to each child, and each of the last five children adds 1 apple, the number of apples for 10 children should be 5, 6, 7, 8, 9, 1 1, 12 respectively. The child who gets the most apples must have at least 15. 6. The bookshelf has three layers, A, B and C. 192 books are placed in * *. First, take out as many books from the first floor as the second floor and put them on the second floor, then take out as many books from the second floor and put them on the third floor, and finally take out as many books from the third floor and put them on the first floor. At this time, a,. Inverse method (bottom-up): the initial state of A, B and C is 88 56 48; After A is given to B, it is 321248; After b is given to c, it is 32 64 96; After C is given to A, it is 64 64; The original books of A, B and C are 88, 56 and 48 respectively; 7. A township has 10. There are less than ten thousand chickens. Coincidentally, the sum of the numbers of each chicken farm is equal to 34. How many chickens are raised in this 10 chicken farm? If the sum of numbers is 34, the number less than 65,438+00,000 can only be four digits. Therefore, the number of chickens in each chicken farm can only be 9, 9, 9, 7 and 9. The number of knowledge 10 is: 7997, 9799, 9979, 9997, 8899, 8989, 8998, 9889, 9898, 9988. Their total is: 94435 (only). 8. In the table below, what is the first number on the left of line 100? 54326789 13 12 1 14 15 1 7 265438+._ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ = 396 (number) and because the smallest number in this numerical table is 2, according to the arrangement law of the series, the number of 1 on the left side of the 100 line is: 396+1+/kloc. Two children walk against the escalator, and the boy walks every second. As a result, from one end of the escalator to the other, the boys walked 100 second and the girls walked for 300 seconds. 100 second, how many steps did Boy 3 take? 00=300 (horizontal) The girl walked 2 in 300 seconds? 00=600 (horizontal) means that the escalator moves every second (600-300)? 300- 100) = 1.5 (horizontal), so the escalator has (3- 1.5)? 00= 150 (level) 10. There is an odd number of five digits. In this five-digit odd number, all 2' s are replaced by 5' s, and all 5' s are replaced by 2' s, and the other numbers remain unchanged, thus a new five-digit number is obtained. If half of the new five digits are 1, what are the original five digits? First, the ten thousand digits of the original number. The thousand digits of the original number must be greater than 4, otherwise it will not be carried when multiplied by 2, but the hundred digits can be multiplied by 2 to 1 to thousands at most, so the thousand digits can only be 9. By analogy, the first four digits of the original number can only be 2, 9, 9, 9. Other numbers can only be odd numbers. Upon inspection, the single digit of the original number is 5. So the odd number of the original five digits is 29995. Lonely Sail has 50 pages every day.
