A repost consists of 20 sheets ethof 55 lines and each suchline consists of 65 characters. This report is reduced onto sheetseach of 65 lines such that each line consists: of 70 characters. The percentage reduction in numberofsheetsis closer to
Solution
Total character in 20 sheets of 55 lines each = 20 * 55 * 65
Let the number of sheets after reductio = N
According to the question:
20 * 55 * 65 = N * 65 * 70
N = $$\frac{110}{7} = 15.7 pages = 16 pages$$
Reduction in number of sheets = 20 - 16 = 4 pages
Required percent = $$\frac{4}{20} * 100 = 20$$%
