Question

Числа от 1 до 50 разбили на десять пятерок и в каждой пятёрке выбрали среднее по величине число.какое наибольшее значение может принимать сумма выбранных чисел?

Answer 1

Ответ:

30

Пошаговое объяснение:

1) разбили на 10 пятерок. А потом выбрали среднее по величине число т.е. 3 (от 1 до 5 среднее число 3) и т.к. выбрали всего 10 чисел, значит 10*3=30

Answer 2

Finding the Maximum Sum of Selected Numbers

To find the maximum value of the sum of the selected numbers, we can consider the following approach:

1. Dividing Numbers into Groups: - The numbers from 1 to 50 are divided into ten groups of five numbers each. - The middle number in each group of five is selected.

2. Calculating the Maximum Sum: - We need to determine the maximum possible sum that can be obtained by selecting the middle numbers from each group.

Maximum Sum Calculation

To calculate the maximum sum, we can find the middle numbers in each group and then sum them up.

The middle numbers in the groups are as follows: - Group 1: 3 - Group 2: 33 - Group 3: 13 - Group 4: 23 - Group 5: 43 - Group 6: 7 - Group 7: 17 - Group 8: 27 - Group 9: 37 - Group 10: 47

The maximum sum of these numbers is: 3 + 33 + 13 + 23 + 43 + 7 + 17 + 27 + 37 + 47 = 250

Therefore, the maximum value that the sum of the selected numbers can take is 250.
