Circulation figures (in thousands) of different newspapers (A, B, C, D, E) for five years are given. Newspaper D circulation: 2019→8, 2020→12, 2021→14, 2022→15, 2023→16. In which of the given years was the circulation of the newspaper D close to its average circulation over all the years?
A.2020 and 2021✓ Correct
B.2022 and 2023
C.2022 only
D.2020 only
Explanation
Average circulation of D = (8 + 12 + 14 + 15 + 16)/5 = 65/5 = 13. The years closest to 13 are 2020 (12) and 2021 (14), each off by 1. Hence the answer is 2020 and 2021.
