Manhattan Prep
At a charity fundraiser, 180 of the guests had a house both in the Hamptons and in Palm Beach. If not everyone at the fundraiser had a house in either the Hamptons or Palm Beach, what is the ratio of the number of people who had a house in Palm Beach but not in the Hamptons to the number of people who had a house in the Hamptons but not in Palm Beach?
1) One-half of the guests had a house in Palm Beach.
2) Two-thirds of the guests had a house in the Hamptons.
