A designer completes 3 logos in 4 hours. If she does 2 additional revisions per logo (each takes 20 minutes), total time for 5 logos is ?
Correct answer: C. 10
- A. 8
- B. 9
- C. 10
- D. 11
Explanation
To find the total time for 5 logos, first determine the time per logo. If 3 logos take 4 hours, then 1 logo takes 4/3 hours. For 5 logos, it requires (5 * 4/3) = 20/3 hours, which is approximately 6.67 hours. Each of the 5 logos requires 2 revisions, taking a total of 2 * 20 = 40 minutes per logo, equating to a total revision time of 200 minutes, or 3.33 hours. Adding these, the total time is approximately 6.67 + 3.33 = 10 hours. Thus, Option C is correct. Other options result from miscalculating the time per logo or the total revision time.

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.
