256 A store discounted the sale prices of a coat and a sweater. Is the discounted amount of price of the coat greater than that of the sweater? [E]
1)The discounted percentage of the coat is exactly 2 points greater than that of the sweater.
2)Before discount, the sale price of the coat is $6 less than that of the sweater
叮当意见:
同意.
我理解“discounted amount of price”是指被减掉的价格, 基于此, 1)说coat减价比例大, 2)说coat以前的价格低, 所以E.
我的意见是选C。关键就在discounted amount of price和The discounted percentage 的理解上。
题目:商店降价出售外套和衬衫,降价后的外套比衬衫贵吗?
1)降价后的外套的出售价比例比衬衫大2%。(比如降价后,外套9折,衬衫8.8折)
2)降价前,外套比衬衫贵6块。
设降价前外套是S+6,则 降价后 外套 (S+6)*0.9 衬衫 S*0.88 相减得
S*0.02+5.4》0,所以,回答了问题,YES。
所以,我选C。
其中的比例可以随意,只要是一个比另一个大0.02就行。
请斑竹指正!如果我错了,错在哪里?
谢谢!
