A painter covers a 10x10 wall in 2 hours. A textured wall requires 50% more time. Time to paint 3 textured walls?
Correct answer: D. 9 hrs
- A. 6 hrs
- B. 7.5 hrs
- C. 8 hrs
- D. 9 hrs
Explanation
To solve this problem, first calculate the time to paint one textured wall. A regular wall takes 2 hours, and a textured wall requires 50% more time, which adds 1 hour (50% of 2 hours) to the time, making it 3 hours per textured wall. To find the total time for 3 textured walls, multiply the time for one wall by three: 3 hours * 3 = 9 hours. Therefore, the correct answer is 9 hours. Options A, B, and C fail to correctly account for the additional time required for textured walls.

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.
