B completes a job in 5 days. His work rate per day is:
Correct answer: A. 1/5
- A. 1/5
- B. 1/4
- C. 1/3
- D. 1/6
Explanation
The correct answer is 1/5. Since B completes the entire job in 5 days, his work rate is calculated by dividing 1 job by 5 days, resulting in a work rate of 1/5 of the job per day. The other options are incorrect because they suggest completing the job in a different number of days: 1/3 implies 3 days, 1/4 implies 4 days, and 1/6 implies 6 days.

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.
