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 increase in production of steel in 2023 over the preceding year is how many times compared to the increase in production of steel in 2021 over its preceding year?

2.50

1.50

1.25

2.75

✅ Correct Option: 3

Increase in 2023 over 2022: $438-393=45$. Increase in 2021 over 2020: $382-346=36$. Required number of times: $\dfrac{45}{36}=1.25$. Therefore, the increase in 2023 was 1.25 times the increase in 2021.

Question 25

How many years have shown production of steel above the average production for the given period (2017-2024)?
