［酥雪］碰到好多啊。。。大部分碰到的都出现在1-100里，大家时间紧的话仔细看看。
以下是跟jj里一样的（我尽量回忆。。。）
－ 等边三角形外切、内切圆r的ratio：1:4
－ 那到等腰梯形上底下底6,8, 内切于一个圆，圆半径是5，求提醒面积：原题有图，答案是49
－ 打车前1/7 mile 0.56刀（数字忘了，好像是0.5几），after that: 0.33usd for any addional 1/7 miles or thereof。问4.6（忘了。。好像是这个数）mile 多少钱。A. 2刀多， B-E 都是9刀以上。我选了第一个。。。但是算了好几次。。。感觉都不太对，但是都是2点几。。。
－ DS: 问能不能判断一个连续数列里有多少个数， promt: median = mean。1) the smallest is 5; 2) the biggest is 15。 答案是D, each alone is sufficient
－ 有道DS求一个长方形减去两个对称三角形(变长是a,b）的面积
－ DS: yellow, blue, red三种颜料，混合后组成一个new color，问new color里yellow的ratio能不能算出来？ 1) 给了new color里，red，blue and yellow的关系，可以列出两个方程；2）给了new color里yellow的百分比还是什么的。。。感觉两个都可以算。。。不确定啊
－ 那道答对题了得5分，打错了扣1分，一共50题，以下哪个是可能得分数。答案是147好像？
－那道matt and michael从一个300 ft * 160 ft的操场出发那道，答案里没有带根号的，所以jj version 1不用看了，答案是40？反正是整数
［坐稳awwwww］a city implemented a ridership increase plan by investing in both the 82nd and the 102nd street station neighborhoods. After 5 years (?!忘了), the ridership in 82nd increased by 15 % while the increase in ridership in the 102nd neighborhood is only 30%. Thus, the city concludes that the investment in the 102nd station neighborhood is more effective than the investment in the 82nd station neighborhood. Additionally, the city is planning to redirect all the remaining funds from the 82nd to the 102nd in the future.
