Bobby bought two shares of stock, which he sold for $96 each.  If he had a profit of 20 percent on the sale of one of the shares but a loss of 20 percent on the sale of the other share, then on the sale of both shares combined Bobby had

(A) a profit of $10
(B) a profit of $8
(C) a loss of $8
(D) a loss of $10
(E) neither a profit nor a loss

如果一个有20% profit, 另一个有20%的loss，而销售价格又是一样的。那这个答案就肯定选E了，同学们你绝的呢。
