The answer is E. Drawing a Venn Diagram would make this easier, we need to know the Total number of people to use (1) or (2), and that is not given here.

(1) One-half of the guests own a house in Palm Beach.

(2) Two-thirds of the guests own a house in the Hamptons.

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

Look at the diagram below for (1)+(2):

We should find the ratio of yellow boxes, but with the info given it's not possible.
