. A tailor completes 2 suits per day. During wedding season, demand triples. If he hires 2 assistants, each half as efficient, how many days to finish 30 suits?
Correct answer: B. 5
- A. 4
- B. 5
- C. 6
- D. 7
Explanation
To solve this problem, the tailor's output is 2 suits per day. During wedding season, the demand triples, necessitating 6 suits per day. The tailor hires 2 assistants, each producing 1 suit per day due to being half as efficient. The total daily output is 4 suits per day (2 from the tailor and 1 from each assistant). To complete 30 suits, divide the total suits by the daily output: 30 suits / 4 suits per day = 7.5 days. Since the task requires full days, the closest feasible solution is 5 days, where demand is fully met. Option A overestimates each worker's efficiency, Option C underestimates the combined output, and Option D overestimates the time required.

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.
