楼主辛苦了
177. 我遇到的是問%
如果提供的答案沒錯 4/23= 17%
141. There are 100 pounds of fruit and water in the fruit is 99% by weight. After the fruit are dried and some water evaperates, water in the fruit is 98% by weight. How does the water weigh after the fruit are dried.40 50 60,选了50
这道题什么思路,有空指点一下
141. 说有一群人,男人和女人(...废话),这群人里有人有学位,问男人没有degree的是否比女人有degree 的女人多?(类似127)
(1)有8个男人,一共有7个人有学历
(2)男人比有学历的人多.(貌似)
答案: D 這題跟121很像,但是121題答案是E
謝謝...
请求楼主可以继续更新啊。。。
