The difference between the two numbers is 49.23. Moving the decimal point of the smaller number one place to the right is equal to the larger number. Then the sum of the two numbers is () A. 65.64B. 60.28C. 60.17D. 54.7

49.23 △ 10-1, = 49.23 △ 9, = 5.47; 5.47 × (1 + 10) = 60.17; therefore, C

20. The teacher wrote 13 natural numbers on the blackboard and asked Xiao Wang to calculate the average (with two decimal places). The answer Xiao Wang calculated was 12.43. The teacher said that the last number was wrong and the other numbers were all right. What's the correct answer? The teacher said that the last number was wrong and all the other numbers were right The average value must be greater than 12.4 and less than 12.5 12.4*13=161.2 12.5*13=162.5 Therefore, the sum of 13 natural numbers is greater than 161.2 and less than 162.5, and they are also natural numbers So the sum of these 13 numbers can only be 162 So the average is 162 / 13 = 12.46 You have a good way to solve it
