What is the maximum number of questions in the Mechanical category?

• A. The exact number is not specified, but it is part of the overall 65 questions.
• B. Exactly 20 questions.
• C. Exactly 10 questions.
• D. There are no Mechanical questions.

Answer: (A)

The main idea here is that the test has a fixed total of questions, but how those questions are spread across categories isn’t given. Since the overall number of questions is 65, there’s no stated breakdown that fixes how many of those must be Mechanical questions. So you can’t determine a precise maximum for Mechanical from the information provided. The only supported statement is that Mechanical questions are part of the total 65.

The other possibilities would require a specific distribution that isn’t provided: fixing Mechanical at 20 or at 10 would imply particular allocations for the other categories to still total 65, which isn’t given. Saying there are no Mechanical questions would contradict the premise that Mechanical is a category on the test.
