求教一小六数学题字义

Daisy had 3/4 as much money as Vijay after spending $25 on a bag.  这句的意思是 Saisy 还是Vijay 谁买了 bag? 我觉得有点混乱呢,哪位亲,帮我顺顺 。

应该是Daisy买了包。

Daisy had 3/4 as much money as Vijay after spending $25 on a bag.
1. Daisy has $x initially, eg. $100
2. He spent $25 on a bag, so he has $ now as = x – 25, which is 100 – 25 = $75
3. His money is 3/4 of Vijay now, which means Vijay’s = ( x – 25 ) * 4 / 3 =  75 * 4 / 3 = $100

这种题目不好出就是因为这些容易产生歧义的句子,如此出题人仔细点,应该用After spending $25 on a bag, Daisy had 3/4 as much money as Vijay.

确实容易产生歧异。不过如果分析英语语法的话,如果是指Vijay,就应该跟动词spent,而题目里用的after spending,所以只能是Daisy

谢谢大家,

主语是Daisy 所以其实不很复杂 =)

daisy花了25买了包,他的钱相比vijay是3/4.
但是没法确定两个人都有多少钱,还缺个条件。

Daisy买的包,从语法看,其实毫无问题。
