Two confusing choices: 1. it is eastimated that
2. while there are estimated ( my choice)
一道数学。
A sum of money that includes two kinds of coins, 0.25 and 0.05 face value. The total maney is 2.9 dollars. Ask if the number of 0.05 coins is divided by 5, what is the remaining value of money.
choices 4 3 2 1 0 ( i did not figure it out yesterday )
Any one who get a sharp mind and great insight in gmat please help me to crack the two questions, thanks!
谢谢你对语法题的解释，我的第一个选择是it is estimated that. 但当时感觉此题有点过于简单，怀疑有陷阱。 又觉得that后面是三个并列的句子（也许对这种形式的出现比较陌生吧）所以最后选了第二个选项。遗憾！
那道数学题我今天晚上再演练一番，着恐怕是我错的唯一一道数学题。
Thanks a lot, cunning cat! my email adress is uclb5550@sina.com
I will take the test again in next month.
Before i took the last test, i have done all of the material i can get( lsat, gre reading comprehenstion part, all of the gmat questions) But i still got a poor score. I actaully also know what is wrong with me. Not hard wording enough simply two weeks before the test. SHAME. Now i must have to make a strict schedule for myself in order to exhibit my real level. Hope we can change our idea about gmat in future.

-----------------------------
0.25x +0.05y=2.9 =》5x+y=58。5x只能有两种个位：5、0，，当是5时，则Y 的个位是3，当是0时，Y的个位是8，其中3、8都不能被5整除，所以0.05的硬币数不能被5整除，也就是说这个题目绝对有问题。
okay, it is good to let professional to get involved. They may explore its hidden meaning in another way, possibly, redefining it. anyway, thanks a lot, my dear friend!

as the adjuested version , the problem will be
A sum of money that includes two kinds of coins, 0.25 and 0.05 face value. The total maney is 2.9 dollars. Ask if the number of 0.25 coins is divided by 5, what is the remaining value of money.
choices 4 3 2 1 0
right ?
well , I still faid to get the answer
0.25*5t+0.05y=2.9=> 25t+y=58
as t =2 y=8
0.05*8=0.4
none of the alternative choice ....??
lisaislisa: yours is wrong!
0.25t+0.05y=2.9 => 5t + y=58
the digit of 5t must be 0 or 5, consequently that of y must be 8 or 3.
According to the choices 4 3 2 1 0 , we can confirm that the answer is 3
