If a man completes a task in 10 days, how much work does he do in 1 day?
Correct answer: B. 1/10
- A. 10
- B. 1/10
- C. 5
- D. 1/5
Explanation
The correct answer is 1/10. If a man completes a task in 10 days, the amount of work he completes in one day is the reciprocal of the total days, which is 1/10. Option A (10) is incorrect because it suggests he completes 10 tasks per day, which would mean finishing the work in one day. Option C (5) implies completing the task in 1/5 of a day, which is not feasible. Option D (1/5) suggests completing the work in 5 days, which contradicts the given information.

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.
