GMAT数学中一些难懂的语法表达问题

阿狼

In a certain flower shop, which stocks four types of flowers, there are 1/3 as many violets as carnations, and 1/2 as many tulips as violets. If there are equal numbers of roses and tulips, what percent of the flowers in the shop are carnations?
我想问的是there are 1/3 as many violets as carnations 是说1/3violets=carnations, 还是说violets=1/3carnations?

下面还有一题，是我在新东方光盘里面摘录出来的。这题和语法的关系不大，关键应该是在于出售价格和cost的关系吧。
2.A jewelry dealer initially offered a bracelet for sale at an asking price that would give a profit to the dealer of 40 percent of the original cost. What was the original cost of the bracelet?

(1) After reducing this asking price by 10 percent, the jewelry dealer sold the bracelet at a profit of $403.
(2) The jewelry dealer sold the bracelet for $1,953.
答案是A，我当时选的D。现在也想不起来为什么（2）不行了，谁能告诉我呢？

下面还有两个题目，都是新东方光盘里的。我想了想，还是都贴上来了，让大家讨论讨论吧。

3.A grocer is storing small cereal boxes in large cartons that measure 25 inches by 42 inches by 60 inches. If the measurement of each small cereal box is 7 inches by 6 inches by 5 inches, then what is the maximum number of small cereal boxes that can be placed in each large carton?
A  25
B  210
C  252
D  300
E  420
我做的是280，答案是300。呵呵，按最接近的原则来说倒是应该选D。但有哪位XDJM做出300来了，告诉我一声。


4.A computer is programmed to generate a list of multiples of prime numbers 2,3 and 5, as shown below:
Program 1-List multiples of 2
Program 2-List multiples of 3
Program 3-List multiples of 5
How many integers less than 100 will appear on all of the lists of programs produced above?
A  None
B  1
C  3
D  5
E  An infinite number of integers
答案说是C，但计算程序产生负数的话不就应该选E了吗？大家觉得呢？

3.大盒子的体积=25*42*60
  小盒子的体积=5*6*7
  相除=300
  （是不是你想得复杂了？）
4.  2，3，5的公倍数肯定是正的，怎么会是负数呢？

2.asking price 不是实际售价

阿狼

谢谢Louisa_xy了。
但是2的题干中明明说A jewelry dealer initially offered a bracelet for sale at an asking price 啊~~~
那不就是The jewelry dealer sold the bracelet for the asking price 吗？

阿狼

还有题目1中的那个语法表达问题，谁能告诉我啊~~~~~~~

买主有可能砍价的

这个语法问题，很多人都不能确定。你能不能给出答案，倒推一下。

smile1031

"there are 1/3 as many violets as carnations" means : V=1/3C

uclb5550

"there are 1/3 as many violets as carnations" means : V=1/3C
-------------------------------------------------------------------------
能确定吗？

阿狼

根据答案倒推的话，smile1031是对的，就是V=1/3C。
但我记得有道逻辑题，问的是关于某个国家今年和去年生产的纸张数量的比较。其中有个条件说的是twice as much paper produced this year as that produced last year.（大意如此）
但根据答案中的解释来看的话是the amount of paper produced last year is twice the amount of paper produced this year啊~~~
郁闷啊郁闷~~~这到底是怎么回事啊？
