441000 = 36000 (hard copies initial) + hard copies after paperback intro+paperback copies

required info = paperback copies

equation

441000-36000 = H + 9 H

Wanted 9H =(Total Paperback copies) = 364500

Can't understand your question stem for the second question put forward. X does not appear anywhere in question stem . so answer is (A) none.
