  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?

    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.

  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?

    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.

  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?

    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.

  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?

    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%.

  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?

    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.

  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?

    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.
