  1. A table shows the number of students achieving distinction (>75%) in Mathematics over 4 years: 2020=85, 2021=102, 2022=96, 2023=115. What is the range?

    Answer: 30

    Range = highest - lowest = 115 - 85 = 30.

  2. A graph shows that 360 out of 800 first-year students pass their first semester. What percentage failed?

    Answer: 55%

    Passed: 360. Failed: 800 - 360 = 440. Percentage failed: (440 ÷ 800) × 100 = 55%.
