A report consists of 20 sheets each of 55 lines and each such line consists of 65 characters. This report is retyped into sheets each of 65 lines such that each line consists of 70 characters. The % reduction in the number of sheets is closest to

a)20

b)5

c)30

d)35

• total no of characters= 20*55*65.
  from the problem it is clear that 20*55*65=x*65*70
  we get x= 15.6 .we round it to 16 because these are sheets.
  therefore 4 less sheets. so 20% decrease

• ans:20
  total characters=20*55*65=71500
  the no of sheets if we arrange these into 65 lines each contain 70 characters =71500/4550=15.7 pages
  4500=65*70
  so the reduced pages %=4.3/20*100=21.5(~20)
