Work done is directly proportional to:
Correct answer: B. Efficiency
- A. Time
- B. Efficiency
- C. Area
- D. Volume
Explanation
Work done is directly proportional to efficiency because efficiency measures how effectively a task is performed. Higher efficiency means more work can be completed in a given time. Time, although a factor, doesn't guarantee more work unless efficiency is constant, making it an indirect factor. Area and volume are not part of the fundamental work-rate relationship unless specified by the problem's context, which is not present in this question.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
