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

Answer is E.

Without knowing the total guests all equations will lead to a answer with a unknown variable.

with the given info the ratio becomes x/2 -180 % 2x/3 -180 where x is the total guests in the party.

Agree with Subha on E)

Together we get

x/2-180 / 2x/3-180

Cant find the ratio

"If not everyone at the fundraiser had a house in either the Hamptons or Palm Beach" This means there are some guestswho dosn't have any house at said places. If we dont have this no. we can not proceed.

If such ppl are K.
Total guests are G. thne using both od the given info we can conclude that..

G = G/2 + 2G/3 - 180 + K

As here are 2 variables, we should have 2 equations. So answer should be E.
Shubham.
590 >> 630 >> 640 >> 610 >> 600 >> 640 >> 590 >> 640 >> 590 >> 590
