A software update installs in 45 minutes. A new optimization improves time by 33%. How long now?
Correct answer: A. 30
- A. 30
- B. 32
- C. 33
- D. 35
Explanation
The original installation time is 45 minutes. A 33% improvement means the installation time is reduced by 33% of 45 minutes. To find this, calculate 33% of 45: (33/100) * 45 = 14.85. For simplicity, round this to 15 minutes. Subtract this 15 minutes from the original 45 minutes to get the new installation time: 45 - 15 = 30 minutes. Therefore, the updated installation time is 30 minutes, making Option A correct. Other options do not accurately reflect a 33% reduction: Option B and Option C suggest a smaller reduction, and Option D suggests an even smaller reduction.

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.
