When the computer screen and printer display are as shown in the figure, the printer runs out of paper. Then 39 sheets of paper were added to the printer, and when both screens showed 80\%, these papers also ran out. Accordingly, how many pages were marked to be printed at the beginning? A) 50 B) 65 C) 75 D) 90 E) 100
