The following table shows the percentage (%) distribution of the number of readers of an IT magazine in the years 2019 and 2023, among the six different cities A–F. Based on the data in the table, answer the question.
| City | Percentage of readers in 2019 | Percentage of readers in 2023 |

| C | 17% | 28% |

| F | 26% | 22% |
If the number of readers from the City-D in the year 2019 and 2023 were 77,400 and 1,14,000 respectively, then what is the difference between the number of readers from City-F in the year 2019 and that in 2023?
Answer and explanation

City D's figures give the totals: readers in 2019 and in 2023. City F then had readers in 2019 and in 2023. The difference is 250800 − 223600 = 27,200; F's share fell, but its number of readers rose because the total grew.
