In a certain city, the ratio of the number of people who purchase newspaper X to the number of people who purchase newspaper Y is 7:1. What percent of the population purchases newspaper Y?
I think the ANS depends on how you understand the Question.
CASE 1 : IGNORE OVERLAP
Here , only the % of people who purchase News Paper Y is asked.
Assuming that we can ignore the overlap (people purchasing both X n Y),
and find only the Y %
A is SUFF.
We have - 73 % of people who read atleast 1 news paper, be it X, be it Y or be it both.
We are given the ratio of X to Y. Y % can be found out.
CASE 1 : OVERLAP CONSIDERED
Here , its E I ges.
correct me if I am wrong.
