If a person works at 75% efficiency, his output is:
Correct answer: A. 3/4
- A. 3/4
- B. 2/3
- C. 1/4
- D. full
Explanation
The correct answer is A. 3/4. If a person works at 75% efficiency, they are completing 75% of the work that would be done at full efficiency. This is equivalent to 3/4 of the standard output. Option B (2/3) represents approximately 66.67% efficiency, which is not the same as 75%. Option C (1/4) represents only 25% efficiency, which is much less than 75%. Option D ('full') represents 100% efficiency, which is greater than 75%.

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.
