A can do a piece of work in 5 days. Work done in 2 days = ?
Correct answer: B. 2/5
- A. 1/2
- B. 2/5
- C. 3/5
- D. 4/5
Explanation
A can complete the entire work in 5 days, so the amount of work done per day is 1/5. In 2 days, the amount of work done is 2 × 1/5 = 2/5, making Option B correct. Option A, 1/2, is incorrect because half the work would take 2.5 days, not 2 days. Option C, 3/5, is incorrect as it represents 3 days of work. Option D, 4/5, is incorrect because it represents 4 days of work.

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.
