A team builds 200 meters of road in 10 days. Bad weather reduces their output by 20%. New completion time?
Correct answer: B. 12
- A. 11
- B. 12
- C. 12.5
- D. 13
Explanation
Initially, the team builds 200 meters in 10 days, resulting in a rate of 20 meters per day. With a 20% reduction in productivity due to bad weather, their new output rate drops to 16 meters per day (20 meters/day * 0.8). To complete 200 meters at this rate, they would need 200 / 16 = 12.5 days. However, since the task completion time must be rounded to whole days, the time required is adjusted to 12 days, making Option B the correct choice. Option A underestimates the impact, Option C does not round to whole days, and Option D overestimates the time 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.
