Ans is C.

Given :

There were 36.000 hardback copies of a certain novel sold before the paperback version was issued. -> H1 = 36 K

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. -> P = 9H2

total of 441.000 copies of the novel were sold in all -> H1 + P + H2 = 441K

Solving,

H1 + P + H2 = 441K ........................( H1 = 36 K)
P + H2 = 441K - 36K = 405K
9H2 + H2 = 405K.............................(P = 9H2)
H2 = 40.5K

Total hardback = H1 + H2 = 36K + 40.5K = 76.5K
P = total - total hardback
P = 441 - 76.5K
P = 364.5K

C.

old post but can someone confirm the OA for this one.
No where does it say that when the first Paper back copy was issued no more hard copies were being sold.
36000 of HC were sold before the first PB was issued , and assuming that after the first PB was issued HC continued to sell.

My equation was based on the following logic: suppose X copies of HC sold between the first and last copies of PB.
Then total PB = 9( 36000 + X) as total PB = 9 * total HC sold.

And Total HC = 36000 + whatever HC sold in between the first and last PB, here we are taking this as X.

hence Final Equation = Total HC + Total PB = 441000
Total HC = 36000 + X
Total PB =9 (36000 +X)

36000 + X + 9(36000 +X) =441000
On solving we get x= 8100
total PB = 9* ( 36000 +8100)
=9 *44100
=396,900
Ans = E
