Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2018 and 2020.
Total export in 2017 = 2000 + 1500 + 1400 = 4900
Total export in 2018 = 4000 + 3000 + 2000 = 9000
Total export in 2019 = 2000 + 1500 + 2000 = 5500
Total export in 2020 = 3000 + 3000 + 3000 = 9000
Total exports in 2021 = 4000 + 3000 + 3000 = 10000
Therefore, the following pairs of years are the total exports from the three companies that was equal in 2018 and 2020.
