Answer 2

Analysis of the Problem

To solve this problem, we need to determine if three people could have eaten more than half of the total number of candies consumed at Petia's birthday party. We know that there were 7 guests in total, including Petia, and that each person ate a different number of candies. Additionally, we know that Petia ate 78 candies.

Solution

To solve this problem, we need to find the total number of candies consumed by all the guests, excluding Petia. Then, we can check if three people could have eaten more than half of that total.

Let's calculate the total number of candies consumed by all the guests, excluding Petia. We'll subtract the number of candies Petia ate from the total number of candies consumed at the party.

Total number of candies consumed by all guests (excluding Petia) = Total number of candies - Number of candies Petia ate

To determine if three people could have eaten more than half of the total, we'll compare this value to half of the total number of candies consumed by all the guests.

If the total number of candies consumed by all the guests (excluding Petia) is greater than twice the number of candies eaten by three people, then three people could have eaten more than half of the total.

Let's calculate the total number of candies consumed by all the guests (excluding Petia) and check if three people could have eaten more than half of that total.

Calculation

Given: - Number of guests at the party (including Petia): 7 - Number of candies Petia ate: 78

Total number of candies consumed by all guests (excluding Petia) = Total number of candies - Number of candies Petia ate

We don't have the exact total number of candies, so we'll need to make some assumptions to proceed with the calculation.

Assumption: - Each guest ate at least one candy.

Based on this assumption, we can calculate the minimum possible total number of candies consumed by all the guests (excluding Petia).

Minimum possible total number of candies consumed by all guests (excluding Petia) = 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28

Now, let's check if three people could have eaten more than half of the minimum possible total.

Half of the minimum possible total = 28 / 2 = 14

Since 14 is less than the number of candies eaten by three people, it is not possible for three people to have eaten more than half of the total number of candies consumed at the party.

Therefore, three people could not have eaten more than half of the total number of candies consumed at Petia's birthday party.

Conclusion

Based on the given information and assumptions, it is not possible for three people to have eaten more than half of the total number of candies consumed at Petia's birthday party.
