Use 10, 20, 30 80 eight numbers, respectively fill in the small circle, so that the sum of five numbers on each big circle is equal to 210

Use 10, 20, 30 80 eight numbers, respectively fill in the small circle, so that the sum of five numbers on each big circle is equal to 210

According to the eight numbers given in the question, we can think as follows: first, add up these eight numbers to get 360, and ask the sum of five numbers in each big circle to be equal to 210, then the sum of two big circles is 420, and the sum of the numbers in the two shared small circles should be 420-360 = 60
