CompTIA Project+ (PK0-004) — Question 550
A homeowner wants to build a fence. It will take:
✑ A quarter of a day to measure the length of the fence
✑ Half a day to acquire the materials
✑ A quarter of a day to dig holes for the posts
✑ A quarter of a day to set the posts with concrete
✑ Two days for the concrete to dry
While the concrete is drying, the homeowner will spend a quarter of a day cutting the lateral pieces to size, half a day applying the coating to the remaining pieces, and then three days waiting for the coating to dry. It will then take the homeowner one day to assemble the fence. Which of the following is the length of time it will take the homeowner to build the fence?
Answer options
- A. Six days
- B. Seven days
- C. Eight days
- D. Nine days
Correct answer: A
Explanation
The total time spent by the homeowner is calculated as follows: measuring (0.25) + acquiring materials (0.5) + digging (0.25) + setting posts (0.25) + drying concrete (2) + cutting pieces (0.25) + applying coating (0.5) + drying coating (3) + assembling (1) equals 8 days. However, since the concrete drying time overlaps with other tasks, the total comes to 6 days. Thus, the correct answer is A, while the others are incorrect as they overestimate the total time needed.
