    This problem appears to be very simple, i guess i am having a bad day!!!

    There were 36.000 hardback copies of a certain novel sold before the paperback version was issued. From the time the first paperback copy was sold until the last copy of the novel was sold. 9 times as many paperback copies as hardback copies were sold. If a total of 441.000 copies of the novel were sold in all, how many paperback copies were sold?
    (A) 45.000
    (B) 360.000
    (C) 364.500
    (D) 392.000
    (E) 396.900

    hi,

    problem says --
    From the time the first paperback copy was sold until the last copy of the novel was sold. 9 times as many paperback copies as hardback copies were sold. So if 'n' is no of hardbacks sold since first paperback copy was sold, then 9n is the no of paperbacks sold.

    total sold=441000
    copies sold since first paperback was sold = 441000 - 36000 = 405000
    this no equals = n + 9n = 10n
    so, no of paperbacks = 9/10 * 405000

    ans = (C)

    hope its clear

    C

    P = 9H

    P+H+36000 = 441000
    10H = 405000
    9H = P = 405000*9/10 = 364,500
