Which speed value is exactly at the upper limit of 200-1000 rpm?

• A. 800 rpm
• B. 1000 rpm
• C. 1200 rpm
• D. 200 rpm

Answer: (B)

The main idea here is identifying the upper limit of a stated range. For the range 200 to 1000 rpm, the highest allowed value is 1000 rpm, so that is the speed exactly at the upper limit. 800 rpm is within the range but not at the top, 200 rpm sits at the lower end, and 1200 rpm lies outside the permitted range.
