  1. A table shows that a factory produced 120 items in January, 150 in February, and 180 in March. If the pattern continues, how many items will be produced in April?

    Answer: 210

    The pattern increases by 30 each month: 120→150→180→210.

  2. A circle graph (pie chart) divides a $500 budget into: Rent 40%, Food 30%, Transport 20%, Other 10%. How much money is allocated to food?

    Answer: $150

    Food = 30% of $500 = 0.30 × $500 = $150.

  3. A line graph shows temperatures over 5 days: Mon=70°F, Tue=65°F, Wed=60°F, Thu=58°F, Fri=62°F. Which best describes the overall trend?

    Answer: Temperatures generally decreased then slightly rose

    Temperatures decreased from Monday through Thursday, then rose slightly on Friday, showing an overall downward trend with a minor uptick.

  4. A bar graph shows book sales by genre: Mystery=450, Fantasy=380, Romance=520, Science Fiction=290. What fraction of total sales does Romance represent (approximate)?

    Answer: About 1/3

    Total = 1640; Romance = 520; 520/1640 ≈ 0.317, which is approximately 1/3.

  5. A data set has values: 10, 20, 30, 40, 50. What is the range of this data set?

    Answer: 40

    Range = largest value − smallest value = 50 − 10 = 40.

  6. A table shows that 3 out of every 12 students bring lunch from home. In a school of 480 students, how many bring lunch from home?

    Answer: 120

    The ratio 3/12 = 1/4; one-quarter of 480 = 120 students.

  7. A scientist records plant growth over 4 weeks: Week 1=2cm, Week 2=4cm, Week 3=8cm, Week 4=16cm. What type of pattern is this?

    Answer: Exponential (doubling) growth

    The plant doubles each week (×2), which is an exponential growth pattern.
