Video Summary

In the given puzzle, numbers 1 to 10 are used to fill circles with specific column and row sums. The total sum of the numbers in the circles is 55. The sums for the left and right columns are both 24, leaving the numbers in the middle column summing to 7. After trying different combinations, it is determined that the middle circle in the bottom row must be 6 to achieve the sum of 25 with maximum corner values. Therefore, the circle with the question mark must contain the number 1 to satisfy all conditions, but this wasn't an option, leading to "none of the previous" as the answer.
