Question: D29

Difficulty: 5 (Moderate)
Category 1: Arithmetic > Percents > other
Category 2: Arithmetic > Sets > 2 sets
Category 3: Word Problems > Sets >

Explanation: Statement (1) is insufficient. We don't know what fraction of retailers owned their own store, and we don't know what percentage of retailers who do not own their own store purchased computers for business purposes. Both would be necessary to answer the question in conjunction with the information given.

Statement (2) is insufficient. It doesn't tell us anything about purchasing computers for business purposes.

Taken together, the statements are insufficient. Combined, they tell us what percentage of retailers own their own store and purchased computers for business purposes. However, we don't know how many retailers who do not own their own store and purchases computers for business purposes. Choice (E) is correct.
