A marketing company doing a survey at a local nightspot asked 44 drinkers about their alcohol preferences. 10 people said they drink only wine, while 4 people said they only drink wine and hard liquor. One-fourth of all the people said they only drink beer, and there was no one that said they only drink beer and wine. If two people each said they drink either all three types of beverage or only liquor and the rest of the people drink only beer and liquor, how many people said they drink don't drink wine?

Answer should be B: 28
Approach:
Out of 44 people- "10 people said they drink only wine", "while 4 people said they only drink wine and hard liquor.", "and there was no one that said they only drink beer and wine", "two people each said they drink either all three types of beverage or only liquor".
SO, by simple calculation,
44-10-4-0-2 = 28 people not drinking wine.
Hope this is the simplest way to get the no. of person not drinking wine. Just subtract the people who are drinking wine from the total count.

Hit +1 Kudos if you like.

To solve this problem, we need to determine the number of people who drink wine because 44 - the number of people who drink wine = the number of people who do not drink wine.
The number of people who drink wine consists of the following four subgroups:
1) People who drink wine only
2) People who drink both wine and beer (but not liquor)
3) People who drink both wine and liquor (but not beer)
4) People who drink all three types of beverages
According to the information given in the problem, we have 10, 0, 4, and 2 in each of the subgroups, respectively. Thus the number of people who don’t drink wine is:
44 - (10 + 0 + 4 + 2) = 44 - 16 = 28
Answer: B
