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?

Two time intervals are considered here.

Before Paperback: 36,000 of hardback sold
We also know that total sold = 441,000; thus, total sold after Paperback = 441,000 - 36,000 = 405,000

After Paperback, we have:
9*H = P
P + H = 405,000
Solve for H: H = 40,500
Solve for P: P = 9*40,500 = 364,500

Easy one:

P = 9H
H + 9H = 441,000 - 36,000
10H = 405,000
H = 40,500
P = 364,500
