52. The following editorial appeared in the Elm
City paper.
“The construction last year of a shopping mall in downtown Oak
City was a mistake. Since the mall has opened, a number of local businesses have closed, and the downtown area suffers from an acute parking shortage, and arrests for crime and vagrancy have increased in the nearby Oak
City
Park. Elm
City should pay attention to the example of the Oak
City mall and deny the application to build a shopping mall in Elm
City.”(新题)

1. A 预测某东东是5.4, B预测是6.3. 现在A比实际值低(below) 4%. 问B比实际值高多少.
2. 47.95=1.73*27.4. 问 47.95/0.00274=?. (具体数字不准确), 答案有1750, 175, 17500之类
3. 一题类似 3^(-4)/6^(-8)=?
4. x^2+y^2=6?有点忘记了是等于还是大于
(i) (x+y)^2>6
(ii)xy=2
5. a,b,c同时做一件事情要一小时,问b单独作要多久?
(i)a,b同做要4/3小时
(ii)b,c同做要3小时
6. l(x)表示比x大于或等于x的最小整数, g(x)表示小于或等于x的最大整数, 问l(x)-g(x)集合
a. {0} b {0,1} c {-1,0}, d {1} e{-1,0,1}
7. a,b,c,d,e5个质数product是4290, 问|e-d| (数字也记不准确了，方法一样的,当时我一下记不住143=11*13了,以为143就是一个质数)
(i) abcd=60
(ii)abc=30
8. g(x)=10000+ax+bx^2, 问b=? (数字不准确)
(i) x=500时, g(x)等于某个知道的数
(ii) x=1000时, g(x)是两倍的g(500)
9. y=a(x+h)^2+K,a<>0,在x上有几个intercept?
(i)h=0
(ii)k=0
10. x^(-y)>1?
(i) x>0
(ii)y>0
11. xy>(x^2)(y^2)?
(i)(2x+3)^2=某个数
(ii)y=1
12. r,s,t. r=u^2+v^, s=2uv, t=u^2=v^2,要用s和t表示r^2
