If A does 1/5 of a work in 1 day, he'll complete it in:
Correct answer: C. 5 days
- A. 3 days
- B. 4 days
- C. 5 days
- D. 6 days
Explanation
The correct answer is 5 days. Since A completes 1/5 of the work each day, multiplying this rate by 5 days results in 5/5 or the entire work being completed. Option A (3 days) and Option B (4 days) are incorrect because they represent fractions of the work done, specifically 3/5 and 4/5, respectively. Option D (6 days) is incorrect because it exceeds the necessary time to finish the work, resulting in 6/5 of the work being done, which is more than needed.

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.
