Explanation
To simplify this problem, ignore the chart column about the greatest single employee donation and plug in easy values for the number of employees for each company.
Try 15 employees for Company A and 1 employee for Company K: Now you have a total donation of 15 × 34.6 = 519 per year from Company A, and a total donation of 104.4 per year from the single employee of Company K.
The ratio is thus 519:104.4, which reduces almost exactly to 5:1, so choice E is correct. If you selected choice (A), you may have solved for the averages rather than the actual amount of the donations; if you selected choice (D), you may have solved for the period 1980–1990.
Hence option E is correct!
