Of the 200 books a used-book store added to inventory last Monday, how many were sold by the end of the week?

(1) The 200 books added represented a 4 percent increase to the stores inventory.

(2) In the week between the addition of the 200 books and the end of the week, the stores inventory decreased by 6 percent.

How come the answer is E and not A?

This is why I think it should be A

Let x be the number of books before 200 were added.

Total inventory (x+200).

200 = 0.04(x+200)

We can calculate x and the difference.

Statement B - doesn't give us any meaningful information.
