A does a job in 6 days. B does the same job in 3 days. Who is more efficient?
Correct answer: B. B
- A. A
- B. B
- C. Same
- D. Depends on work
Explanation
The correct answer is B. Efficiency is determined by how quickly a task can be completed. Since B completes the job in 3 days while A takes 6 days, B is more efficient. Option A is incorrect because A takes longer to do the same work. Option C is incorrect because the time taken by A and B is different, indicating different efficiency levels. Option D is incorrect because the job is identical for both A and B, allowing for a direct comparison of efficiency based solely on time.

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.
