A street artist finishes a mural in 10 days working 6 hours a day. If he works 8 hours a day, how many days does he need?
Correct answer: C. 7.5
- A. 6
- B. 7
- C. 7.5
- D. 8
Explanation
The street artist originally finishes the mural in 60 hours (10 days x 6 hours). If he works 8 hours a day, we calculate the new number of days as follows:New days = Total work / New hours per day = 60 hours / 8 hours per day = 7.5 days.This means that 7.5 days are required when working 8 hours per day.Option A (6 days) is incorrect because it underestimates the time needed. Option B (7 days) is also incorrect as it does not consider the additional half day required. Option D (8 days) overestimates the time required.

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.
