[求助]陈向东第五章-39题

littleblues

陈向东对这道题目意思的理解自相矛盾：他把the reduced price理解成减少的钱（即10-2=8中的2），却把the increased price理解成涨价后的钱（即8+2=10中的10），难道“加”和“减”还有这样的区别？？？

大家给点意见吧，是不是老陈弄错了？正确的理解应该是怎样的呢？我觉得第二个理解是正确的。还有，如果想要用英文来表达第一种理解（即那个被减去的2），应该如何来表达呢？

littleblues

The price per share of stock X increased by 10 percent over the same time period that the price per share of stock Y decreased by 10 percent. The reduced price per share of stock Y was what percent of the original price per share of stock X?

(1) The increased price per share of stock X was equal to the original price per share of stock Y.

(2) The increase in the price per share of Stock X was 10/11 the decrease in the price per share of stock Y.
