80% = 704 papers
1% = 8.8
100% = 880
So total number of papers published were = 880
Out of these 880, 80% (704) were affected.
In 2016
Increase in number of papers = 10% of 880 = 88
Total number of papers published = 880 + 88 = 968
Increase in number of pages with errors = 20% of 704 = 140.8
Total number of pages with errors = 704 + 140.8 = 844.8
In 2017
Increase in number of papers = 10% of 968 = 96.8
Total number of papers published = 968 + 96.8 = 1064.8
Increase in number of pages with errors = 20% of 844.8 = 168.96 ≈ 169
Total number of pages with errors = 844.8 + 169 = 1013.8
In 2018
Increase in number of papers = 10% of 1064.8 = 106.48
Total number of papers published = 1064.8 + 106.48 = 1171.28
Increase in number of pages with errors = 20% of 1013.8 = 202.76
Total number of pages with errors = 1013.8 + 202.76 = 1216.56
The number of pages with errors exceeds the total number of pages published in 2018. So C is the answer.
