  1. A double bar chart shows male and female applicants per department: HR (M=20, F=40), IT (M=60, F=30), Finance (M=25, F=35). Which department has the highest total applicants?

    Answer: IT

    IT total = 90, HR total = 60, Finance total = 60, making IT the highest.

  2. A line graph shows website traffic over 5 days: Mon=1,200, Tue=1,500, Wed=900, Thu=1,800, Fri=1,600. What is the median daily traffic?

    Answer: 1,500

    Sorted values: 900, 1200, 1500, 1600, 1800 — the middle value (3rd) is 1,500.

  3. A stacked bar chart shows total project hours split between development and testing: Project A (Dev=120, Test=30), Project B (Dev=80, Test=70). What percentage of Project B's hours were spent on testing?

    Answer: 46.7%

    Testing share = 70/(80+70) = 70/150 = 46.7%.

  4. A table shows unit costs at different production volumes: 100 units=$50, 500 units=$40, 1,000 units=$32, 5,000 units=$25. This pattern best illustrates:

    Answer: Economies of scale

    Decreasing unit cost as volume increases is the classic definition of economies of scale.

  5. A pie chart shows budget allocation: Salaries=60%, Marketing=20%, Operations=12%, R&D=8%. If the total budget is $5M, how much more is spent on Salaries than on Marketing and Operations combined?

    Answer: $1,400,000

    Salaries=$3M; Marketing+Operations=($1M+$0.6M)=$1.6M; difference=$1.4M.

  6. A bar graph shows quarterly revenue for two years. Q3 Year 1=$80K and Q3 Year 2=$68K. What is the percentage decrease?

    Answer: 15%

    Decrease = (80−68)/80 × 100 = 12/80 × 100 = 15%.

  7. A data table has missing values. Row totals are 50, 70, 80 and the grand total is 200. One row sub-total shows 45 with a missing second column value. What is the missing value?

    Answer: 5

    The missing value = row total (50) − known sub-total (45) = 5.
