461. stock x 面值40, stock y 面值25, 到当天交易结束时, x售出价是41, y的售出价是28.5, 问 the percentage increase of y stock is what percentage point greater than the percentage increase of stock x? 我是这么做的: (28.5-25)/25-(41-40)/40=0.115 因为问的是多多少个百分点(percentage point),所以选11.5
同意
问 the percentage increase of y stock is what percentage point greater than the percentage increase of stock x?不是要0.115/(41-40)/40么?y增加的部分比x增加部分多百份之多少。理解有问题?
