Guests at a recent party ate a total of fifteen hamburgers. Each guest...
For this overlapping set problem, we want to set up a two-set table to test our possibilities. Our first set is vegetarians vs. non-vegetarians; our second set is students vs. non-students.
We are told that each non-vegetarian non-student ate exactly one of the 15 hamburgers, and that nobody else ate any of the 15 hamburgers. This means that there were exactly 15 people in the non-vegetarian non-student category. We are also told that the total number of vegetarians was equal to the total number of non-vegetarians; we represent this by putting the same variable in both boxes of the chart.
The question is asking us how many people attended the party; in other words, we are being asked for the number that belongs in the bottom-right box, where we have placed a question mark.
The second statement is easier than the first statement, so we'll start with statement (2).
(2) INSUFFICIENT: This statement gives us information only about the cell labeled "vegetarian non-student"; further it only tells us the number of these guests as a percentage of the total guests. The 30% figure does not allow us to calculate the actual number of any of the categories.
SUFFICIENT: This statement provides two pieces of information. First, the vegetarians attended at the rate, or in the ratio, of 2:3 students to non-students. We're also told that this 2:3 rate is half the rate for non-vegetarians. In order to double a rate, we double the first number; the rate for non-vegetarians is 4:3 We can represent the actual numbers of non-vegetarians as 4a and 3a and add this to the chart below. Since we know that there were 15 non-vegetarian non-students, we know the missing common multiple, a, is 15/3 = 5. Therefore, there were (4)(5) = 20 non-vegetarian students and 20 + 15 = 35 total non-vegetarians (see the chart below). Since the same number of vegetarians and non-vegetarians attended the party, there were also 35 vegetarians, for a total of 70 guests.
The correct answer is A

Guests at a recent party ate a total of fifteen hamburgers. Each guest...
Given that half of the guests were vegetarians and that each guest who was neither a student nor a vegetarian ate exactly one hamburger, we need to determine the total number of guests at the party.
Statement 1: The vegetarians attended the party at a rate of 2 students to every 3 non-students, half the rate for non-vegetarians.
This statement provides information about the ratio of vegetarian students to non-student vegetarians. However, it does not provide any information about the total number of vegetarians or non-vegetarians. Therefore, statement 1 alone is not sufficient to answer the question.
Statement 2: 30% of the guests were vegetarian non-students.
This statement provides information about the proportion of vegetarian non-students among the guests. However, it does not provide any information about the total number of vegetarians or non-vegetarians, or the total number of guests. Therefore, statement 2 alone is not sufficient to answer the question.
Statements 1 and 2 together:
Combining the information from both statements, we know that the vegetarians attended the party at a rate of 2 students to every 3 non-students, and that 30% of the guests were vegetarian non-students.
From statement 2, we can infer that the remaining 70% of the guests were either vegetarian students or non-vegetarian guests.
Let's assume there were a total of 100 guests:
- 30% of the guests (30 guests) were vegetarian non-students.
- The remaining 70% of the guests (70 guests) were either vegetarian students or non-vegetarian guests.
From statement 1, we know that the vegetarians attended at a rate of 2 students to every 3 non-students. If we assume that the ratio of vegetarian students to non-student vegetarians is 2:3, we can calculate the number of vegetarian students and non-student vegetarians as follows:
- Vegetarian students: (2/5) * 70 = 28 students
- Non-student vegetarians: (3/5) * 70 = 42 non-students
Adding up the number of vegetarian non-students, vegetarian students, and non-student vegetarians, we get:
30 + 28 + 42 = 100 guests
Therefore, both statements together are sufficient to determine the total number of guests at the party.
Hence, the correct answer is option A.
Statement 1: The vegetarians attended the party at a rate of 2 students to every 3 non-students, half the rate for non-vegetarians.
This statement provides information about the ratio of vegetarian students to non-student vegetarians. However, it does not provide any information about the total number of vegetarians or non-vegetarians. Therefore, statement 1 alone is not sufficient to answer the question.
Statement 2: 30% of the guests were vegetarian non-students.
This statement provides information about the proportion of vegetarian non-students among the guests. However, it does not provide any information about the total number of vegetarians or non-vegetarians, or the total number of guests. Therefore, statement 2 alone is not sufficient to answer the question.
Statements 1 and 2 together:
Combining the information from both statements, we know that the vegetarians attended the party at a rate of 2 students to every 3 non-students, and that 30% of the guests were vegetarian non-students.
From statement 2, we can infer that the remaining 70% of the guests were either vegetarian students or non-vegetarian guests.
Let's assume there were a total of 100 guests:
- 30% of the guests (30 guests) were vegetarian non-students.
- The remaining 70% of the guests (70 guests) were either vegetarian students or non-vegetarian guests.
From statement 1, we know that the vegetarians attended at a rate of 2 students to every 3 non-students. If we assume that the ratio of vegetarian students to non-student vegetarians is 2:3, we can calculate the number of vegetarian students and non-student vegetarians as follows:
- Vegetarian students: (2/5) * 70 = 28 students
- Non-student vegetarians: (3/5) * 70 = 42 non-students
Adding up the number of vegetarian non-students, vegetarian students, and non-student vegetarians, we get:
30 + 28 + 42 = 100 guests
Therefore, both statements together are sufficient to determine the total number of guests at the party.
Hence, the correct answer is option A.
