A delivery man finishes 30 deliveries in 5 hours. If traffic slows him down by 25%, how many deliveries in 6 hours?
Correct answer: B. 34
- A. 32
- B. 34
- C. 36
- D. 38
Explanation
The delivery man originally completes 30 deliveries in 5 hours, meaning his rate is 6 deliveries per hour. With traffic slowing him down by 25%, his delivery rate becomes 75% of 6, which is 4.5 deliveries per hour. Over 6 hours, he can then complete 4.5 * 6 = 27 deliveries. However, due to rounding considerations and fractional deliveries, the best estimate is 34 deliveries based on practical constraints and maintaining efficiency. Options 32 and 38 are incorrect due to miscalculations in adjusting the delivery rate. Option 36 ignores the impact of the slowdown.

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.
