Correct Answer: E
Explanation:
Arithmetic Percents
- (1) With only this, it cannot be known what percent of the retailers not owning their own store had purchased computers, and so it cannot be
known how many retailers purchased computers overall; NOT sufficient.
- (2) While this permits the percent of owners and non owners in the survey to be deduced, the overall percent of retailers who had purchased
computers cannot be determined;NOT sufficient.
Using the information from both (1) and (2), the percent of surveyed owner-retailers who had purchased computers can be deduced, and the
percent of non owner-retailers can also be deduced. However, the information that would permit a determination of either the percent of
non owner-retailers who had purchased computers
or the overall percent of all retailers (both owners
and non owners) who had purchased computers is
still not provided.
The correct answer is E; both statements together are still not sufficient.
