  1. A bar chart shows monthly sales: Jan = R12 000, Feb = R15 000, Mar = R9 000. By how much did sales change from February to March?

    Answer: Decreased by R6 000

    Sales went from R15 000 in Feb to R9 000 in Mar, a decrease of R6 000.

  2. A pie chart shows that 40% of students chose Mathematics, 35% chose Science, and the rest chose History. What percentage chose History?

    100% − 40% − 35% = 25% chose History.

  3. A line graph shows a company's profit rising steadily from R200 000 in 2019 to R500 000 in 2023. What is the average annual increase?

    Answer: R75 000

    Total increase = R300 000 over 4 years; average annual increase = R300 000 ÷ 4 = R75 000.

  4. A table shows that a shop sold 120 units at R25 each. What is the total revenue shown in the table?

    Answer: R3 000

    Total revenue = 120 × R25 = R3 000.

  5. In a dual bar chart comparing two schools' results, School A scored 72% and School B scored 84% in Mathematics. What is the difference?

    Answer: 12 percentage points

    84% − 72% = 12 percentage points difference.

  6. A graph shows population growth. In 2000, the population was 4 million; by 2020, it was 6 million. What is the percentage increase?

    Answer: 50%
