Given: Company purchased computers at $2,000 each and printers $300 each
Target question: How many computers did it purchase?
When I SCAN the two statements, they both feel insufficient, AND I'm pretty sure I can identify some cases with conflicting answers to the
target question. So, I'm going to head straight to......
Statements 1 and 2 combined
There are at least two scenarios that satisfy BOTH statements:
Case a: The company bought 10 printers (for a total cost of $3000) and 6 computers (for a total cost of $12,000). In this case, the answer to the target question is
the company purchased 6 computers
Case b: The company bought 30 printers (for a total cost of $9000) and 3 computers (for a total cost of $6,000). In this case, the answer to the target question is
the company purchased 3 computers
Since we cannot answer the
target question with certainty, the combined statements are NOT SUFFICIENT
Answer: E
