A report has 20 sheets each of 55 lines and each line consists of 65 characters. If this report is to be retyped with each sheet having 65 lines and each line of 75 characters what will be the reduction percent in the pages ? (a) 22.5 % (b) 35 (c) 25 (d)none

• let 20 sheets contains 55*65*20 characters which is equals with y pages which contains 65*75*y characters .
  Both the sheets have equal characters so, 20*55*65=y*65*75=>y=14.6 pages means 15 pages
  so reduction in sheets =25%

• 26.67% since 20*55*65=65*75*x so, x=44/3 implies, 100-(220/3)=26.67%

• c)25
  no. of pages required=(20*55*65)/(65*75)=14.66
  as pages cannot be in decimal, so toatal pages required=15
  so decrease=((20-15)/20)*100
