Disclaimer: NTA forgot to print the common data for Questions 25–27 in the candidate response sheet. We reverse-engineered the data based on student memory, so the table below is not the original NTA data. | Year | Steel production | |---|---:| | 2017 | 238 | | 2018 | 267 | | 2019 | 301 | | 2020 | 346 | | 2021 | 382 | | 2022 | 393 | | 2023 | 438 | | 2024 | 471 |

The percent change in production of steel is minimum for which of the following pair of years?

From 2017 to 2018

From 2021 to 2022

From 2018 to 2019

From 2019 to 2020

✅ Correct Option: 2

For each listed pair, use $\text{Percentage change}=\dfrac{\text{new}-\text{old}}{\text{old}}\times100$. | Pair | Change | Percentage change | |---|---:|---:| | 2017 to 2018 | $29$ | $\dfrac{29}{238}\times100\approx12.18\%$ | | 2021 to 2022 | $11$ | $\dfrac{11}{382}\times100\approx2.88\%$ | | 2018 to 2019 | $34$ | $\dfrac{34}{267}\times100\approx12.73\%$ | | 2019 to 2020 | $45$ | $\dfrac{45}{301}\times100\approx14.95\%$ | The smallest percentage change is from 2021 to 2022.
