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 . 请教:问题中的reduced price应该如何理解呢? |
