The table shows the percentage distribution of readers of an IT magazine in 2019 and 2023 across six cities A to F.
| City | 2019 (%) | 2023 (%) |
|---|---|---|
| A | 10 | 15 |
| B | 14 | 16 |
| C | 17 | 28 |
| D | 9 | 10 |
| E | 24 | 9 |
| F | 26 | 22 |
If the total number of readers from all six cities A-F together in the year 2023 was 50,000, then the number of readers was more than 7,400 in exactly how many cities in that year?

Correct answer: (C) 4
Explanation
Exactly 4 cities had more than 7,400 readers, so that is the answer.
A count of 7,400 out of a total of 50,000 is 14.8 percent.
So a city needs a 2023 share above 14.8 percent to exceed 7,400 readers.
City A has 15, City C has 28, City F has 22 and City B has 16 percent, all above 14.8.
City D has 10 and City E has 9 percent, both below 14.8.
So exactly four cities, A, B, C and F, had more than 7,400 readers.
