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
A20
B5
C30
D35
Show Explanation
Given, 20 sheets each of 55 lines and each such line consists of 65 characters. (Condition 1st)
20 sheets, 55 lines and 65 characters = 20*55*65 = 71500 char.
65 lines such that each line consists of 70 characters (Condition 2nd)
So, x sheets,65 lines and 70 characters = x*65*70 char.
Given: This report is retyped
=> x*65*70 = 71500
=> x = 16 sheet.
So reduction %: ([(20-16)*100]/20) *100 =20%

Now new number of sheets required when we have 70 characters in 65 lines=
71500/(70*65) = approx. 16 sheets
So reduction in sheets is 20-16=4
Percentage reduction= (4/20)*100%= 20%
