Step 1: Extract import values from the bar graph
2018: 30, 2019: 45, 2020: 40, 2021: 35, 2022: 50, 2023: 45, 2024: 48.
Step 2: Compute year-on-year falls
- 2020 vs 2019: fall = 45 − 40 = 5. Percentage fall = (5 / 45) × 100 ≈ 11.1%
- 2021 vs 2020: fall = 40 − 35 = 5. Percentage fall = (5 / 40) × 100 = 12.5%
- 2023 vs 2022: fall = 50 − 45 = 5. Percentage fall = (5 / 50) × 100 = 10%
- 2024 vs 2023: this is an increase (no fall).
Step 3: Conclusion
Among the actual falls, the lowest percentage fall is 10% in 2023. However, since 2024 shows an increase (zero fall), the year with the lowest effective fall is 2024.
Answer: 2024
