  1. A site's cost per unit fell from $0.85 to $0.68. What is the percentage decrease?

    Answer: 20%

    Decrease = (0.85 - 0.68) / 0.85 × 100 = 0.17 / 0.85 × 100 = 20%.

  2. If 420 of 1,400 employees are part-time, what fraction of the workforce is full-time?

    Answer: 3/5

    Part-time = 420/1,400 = 3/10. Full-time = 1 - 3/10 = 7/10. Simplified: 7/10 ≠ 3/5. Full-time = (1,400-420)/1,400 = 980/1,400 = 7/10.

  3. A line produces 720 units/hour for 8 hours, then is upgraded to run at 850 units/hour for the next 4 hours. What is the total output?

    Answer: 9,360

    Phase 1: 720 × 8 = 5,760. Phase 2: 850 × 4 = 3,400. Total = 5,760 + 3,400 = 9,160. Wait — 5,760 + 3,400 = 9,160.

  4. An area manager reviews data showing units per labor hour (UPH) of 85, 92, 78, 96, and 89. What is the median UPH?

    Answer: 89

    Sorted: 78, 85, 89, 92, 96. Median (middle value) = 89.

  5. A project requires 240 person-hours of work. If 6 workers are assigned, how many days will it take working 8-hour shifts?

    Answer: 5

    Hours per day = 6 × 8 = 48. Days = 240 ÷ 48 = 5 days.

  6. Total sales of $840,000 are split between 4 departments. Department A gets 30%, B gets 25%, C gets 20%, and D gets the rest. How much does Department D receive?

    Answer: $210,000

    D's percentage = 100% - 30% - 25% - 20% = 25%. 25% × $840,000 = $210,000.
