  1. A report shows that a warehouse processed 1,250 orders last month with a 96% accuracy rate. How many orders contained errors?

    Answer: 50

    Error rate = 4%; 4% of 1,250 = 0.04 × 1,250 = 50 orders with errors.

  2. A line graph shows temperature readings (°F) across five cities: A=72, B=68, C=75, D=80, E=65. What is the range of temperatures shown?

    Answer: 15°F

    Range = highest − lowest = 80 − 65 = 15°F.

  3. A production table shows output per shift: Morning=340 units, Afternoon=295 units, Night=320 units. The afternoon shift wants to reach the average of all three shifts. By how many units must it increase output?

    Answer: 23

    Average = (340+295+320)÷3 = 955÷3 ≈ 318; afternoon needs 318−295 = 23 more units.

  4. A stacked bar chart shows customer complaints by type: billing (45%), delivery (30%), product quality (15%), other (10%). Out of 400 complaints, how many relate to delivery?

    Answer: 120

    30% of 400 = 0.30 × 400 = 120 delivery complaints.

  5. A table shows weekly website visits: Mon=1,200, Tue=980, Wed=1,050, Thu=1,340, Fri=1,100, Sat=870, Sun=760. On which day were visits closest to the weekly average?

    Answer: Friday

    Weekly average = 7,300÷7 ≈ 1,043; Friday's 1,100 is closest to that average.

  6. A comparison table shows two projects' cost overruns: Project A ran 12% over a $250,000 budget; Project B ran 8% over a $400,000 budget. Which project had the larger dollar overrun?

    Answer: Project B ($32,000)

    Project A overrun = 12% × $250K = $30,000; Project B overrun = 8% × $400K = $32,000 — Project B's overrun is larger.
