Analyzing Girls Performance Improvement Year-on-Year
The question asks us to find the year when the performance of girls showed the maximum improvement compared to the previous year. We need to look at the 'Percentage of Girls who passed' column in the provided table and calculate the year-on-year increase.

| 2018 | 32% | 40% |
| 2019 | 42% | 60% |
| 2020 | 55% | 25% |
| 2021 | 40% | 30% |
| 2022 | 60% | 50% |
| 2023 | 42% | 80% |
Calculating Improvement in Girls' Passing Percentage
We will calculate the difference in the percentage of girls passing between consecutive years. An increase in this percentage indicates an improvement in performance.
- 2018 to 2019: The percentage of girls passing increased from 32% to 42%.
Improvement = $\text{42\%} - \text{32\%} = \text{10\%}$ - 2019 to 2020: The percentage of girls passing increased from 42% to 55%.
Improvement = $\text{55\%} - \text{42\%} = \text{13\%}$ - 2020 to 2021: The percentage of girls passing decreased from 55% to 40%.
Change = $\text{40\%} - \text{55\%} = -\text{15\%}$ (This is a decrease, not an improvement) - 2021 to 2022: The percentage of girls passing increased from 40% to 60%.
Improvement = $\text{60\%} - \text{40\%} = \text{20\%}$ - 2022 to 2023: The percentage of girls passing decreased from 60% to 42%.
Change = $\text{42\%} - \text{60\%} = -\text{18\%}$ (This is a decrease, not an improvement)
Identifying Maximum Improvement Year
Comparing the calculated improvements:
- Improvement in 2019: 10%
- Improvement in 2020: 13%
- Improvement in 2022: 20%
The largest increase in the percentage of girls passing occurred between 2021 and 2022, which is a 20% improvement. Therefore, the performance of girls showed maximum improvement in the year 2022 compared to the previous year.
