A REPORT CONSIST OF 20 SHEETS EACH OF 55 LINES AND EACH SUCH LINES CONSISTS OF 65 CHARACTER.THIS REPORT IS RETYPED INTO SHEET EACH OF 65 LINES SUCH THAT EACH LINE CONSISTS OF 70 CHARACTERS. THE % REDUCTION IN THE NUMBER OF SHEETS IS CLOSETS TO
A-20
B-5
C-30
D-35

• In second case, no of sheets reqd= (55*20*65)/(65*70) = 15. 71 sheets or 16 sheets
  Reduction in sheets = 4.
  % REDUCTION IN THE NUMBER OF SHEETS =100*4/20 =20%

• 20x55x65=Kx65x70
  so
  k=15.71
  reduction=20-15.71
  %=[(20-15.71)/20]*100
  hence 21.45 % which is nearest to 20 %
