Question 1: A community center's budget for a renovation project is $12,500. If 30% of the budget is allocated for plumbing, 45% for electrical work, and the remainder for painting, how much money is allocated for painting?
- $2,500
- $3,125 (Correct answer)
- $4,375
- $5,625
Correct answer: $3,125
First, calculate the total percentage allocated to plumbing and electrical work: 30% + 45% = 75%. The remaining percentage for painting is 100% - 75% = 25%. To find the amount for painting, calculate 25% of the total budget: 0.25 * $12,500 = $3,125.
Question 2: An inventory clerk can stock 15 boxes per hour. If the clerk works for 6.5 hours, but takes a 30-minute break, how many boxes will be stocked?
- 97.5 boxes
- 90 boxes (Correct answer)
- 82.5 boxes
- 105 boxes
Correct answer: 90 boxes
The clerk's total work time is 6.5 hours minus the 30-minute (0.5 hour) break, which equals 6 hours of work. To find the total boxes stocked, multiply the stocking rate by the actual work hours: 15 boxes/hour * 6 hours = 90 boxes.
Question 3: A set of blueprints has a scale of 1 inch : 5 feet. If a wall is represented as 4.5 inches long on the blueprint, what is the actual length of the wall?
- 20.5 feet
- 22.5 feet (Correct answer)
- 18 feet
- 25 feet
Correct answer: 22.5 feet
To find the actual length of the wall, multiply the length on the blueprint by the scale factor. The calculation is 4.5 inches * 5 feet/inch = 22.5 feet.
Question 4: A company's sales increased from 250 units in the first quarter to 325 units in the second quarter. Which of the following represents the percentage increase in sales?
- 25%
- 75%
- 30% (Correct answer)
- 23%
Correct answer: 30%
The formula for percentage increase is ((New Value - Original Value) / Original Value) * 100. The increase in units is 325 - 250 = 75. The percentage increase is (75 / 250) * 100 = 0.30 * 100 = 30%.
Question 5: A technician needs to cut a 12-foot pipe into smaller pieces measuring 1.5 feet each. If each cut takes 2 minutes, what is the total time required to cut the entire pipe into the required number of pieces?
- 16 minutes
- 14 minutes (Correct answer)
- 12 minutes
- 18 minutes
Correct answer: 14 minutes
First, determine the number of pieces: 12 feet / 1.5 feet/piece = 8 pieces. To get 8 pieces, you need to make 7 cuts. Finally, calculate the total time: 7 cuts * 2 minutes/cut = 14 minutes.
Question 6: In a quality control check, a batch of 800 components is inspected. If 4% of the components are found to be defective, how many components passed the inspection?
- 768 (Correct answer)
- 32
- 750
- 780
Correct answer: 768
First, calculate the number of defective components: 800 * 0.04 = 32. Then, subtract the number of defective components from the total to find the number of components that passed: 800 - 32 = 768. Alternatively, if 4% are defective, 96% passed. So, 800 * 0.96 = 768.
