Question was something like dz...

A user type a content on 20 sheets, each sheet consist of 55 lines, and each line can have 65 characters. The content is again retyped on a record which is having 71 pages of 65 lines and each line can take 70 characters . How many lines of a record will be free?

a. 18 b,c,d(dnt remember)

if anyone know d exact question please post it and tell me 18 is correct or not??

• if it is asking for no of pages will be free then
  20*55*65= 65*70* (no of page)
  no of page= 110/7 = 15.7 = 16 pages
  71-16=55(ans)
  if it is asking for no of lines will be free in one page then
  20*55*65=70*71*(no of lines)
  no of lines=14.38= 15 lines
  no of lines will be free on each page=65-15=50(ans)

• 20*65*55=71500
  71*65*70=323050

• They are asking for number of lines not pages.
  No. of Lines=?
  Typed Content= (20sheets*55lines*65characs)characters
  =71500
  Total num of lines in New Content = 71*65 =4615 of which each line can have 70 character.
  Therefore, 71500 = 7000+1400+70+30
  = 100lines+20lines+1line+1 partially filled line = 122 lines filled
  Therefore,
  Lines of a record left = 4615-122=4493 lines left

• Total content on first sheet = 20 * 55 * 65 = 71500 (characters)
  Total space in second sheet = 71 * 65 * 70 = 323050 (characters)
  
  Total space left in second sheet after typing content of first sheet = 323050 - 71500 = 251550
  
  So, total characters free = 251550 characters ( = total pages * total lines in a single page * total chars in a single line)
  So, total lines free = 251550 / 70 = 3593.57 lines ( = total pages * total lines in a single page)
  So, total pages free = 251550 / (70 * 65) = 55.285 pages

• Total no of character in previous copy= 65*55*20;
  In new copy:
  70 character in 1 line
  so, 65*55*20 character will in (65*55*20)/70;
  So no of free lines in new copy = (65*71) - ((65*55*20)/70)
  = 3593.57
  = 3593
