⟩ 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 toa) 20b) 5c) 30d) 35
20% is d ans
20*55*65 = 71500 chars
Let the number of sheets required be x here.
Hence, x*65*70 = 71500 chars
or x = 71500/65*70 = 15.71 = 16 sheets(approx)
hence % reduction in sheets = 20%
