There were 36.000 hardback copies of a certain novel sold [#permalink] New post 09 Dec 2003, 15:25
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

Ans = 364500, C

x --> # of hardback copies sold after paperback copies started to be issued
9x --> paperback copies sold

(So, 36000 + x) + (x) = 441000

So, 9x = 364500

i think the answer is E

Let us say H is no of hardcover copies sold after first 36,000 copies
The stem says no of paper back copies sold = 9*(H+36,000)

H + 36000 + 9*(H+36000) = 441000
H = 8100

H+36000 = 44100
so P = 44100 * 9 = 396,900

I agree with anandnk. I also got 396900 with a similar reasoning.

Bhai,

What is the official answer to this?



Anand,

You applied the following reasoning:

Quote:
Let us say H is no of hardcover copies sold after first 36,000 copies
The stem says no of paper back copies sold = 9*(H+36,000)


The question stem says the following:

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.

Looking at the bold portion in the question, I think the equation would be

36000 + H + 9H = 441000

This gives answer C.

Had the question said that the number of paperback copies were 9 times the TOTAL number of hard cover copies sold, your reasoning would be fine.

What do you think?
