A part-time worker completes a data entry task in 6 evenings. On the 3rd evening, power outage reduces work to 50%. How many evenings now needed?
Correct answer: C. 8
- A. 7
- B. 7.5
- C. 8
- D. 8.5
Explanation
The task is originally planned to be completed in 6 evenings, with each evening contributing 1/6 of the total work. On the 3rd evening, only 50% of the work is done due to a power outage, completing only 1/12 of the task instead of 1/6. This leaves 1/12 of the task unfinished, which requires one additional evening to complete. Hence, the total number of evenings required is 8. Option A assumes insufficient additional time, Option B suggests an unrealistic fraction of an evening, and Option D overestimates the required extra 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.
