A video editor completes a 60-minute film in 12 hours. With new software, editing becomes 20% faster. New time required?
Correct answer: A. 9.6 hrs
- A. 9.6 hrs
- B. 10 hrs
- C. 10.5 hrs
- D. 11 hrs
Explanation
The original time taken to complete the editing is 12 hours. With the new software, the editing becomes 20% faster, meaning the time required is reduced to 80% of the original time (100% - 20% = 80%). To find 80% of the original 12 hours, multiply 12 by 0.8, which equals 9.6 hours. Therefore, the correct answer is Option A: 9.6 hrs.Options B, C, and D are incorrect as they do not correctly apply the reduction due to the increased speed. Option B assumes a 16.67% reduction instead of 20%, Option C assumes a 12.5% reduction, and Option D assumes an 8.33% 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.
