先说明,我这里的GWD31的卷子,与版里面的讨论帖汇总的题目,完全对不起来!!! 其次,这道题版内没有人讨论
其实……我就是怎么都没看懂题目:
Q19: A total of $60,000 was invested for one year.But of this amount earned simple annual interest at the rate of x percent per year, and the rest earned simple annual interest at the rate of y percent per year.If the total interest earned by the $60,000 for that year was $4,080, what is the value of x? (1)x = (3/4) y (2)The ratio of the amount that earned interest at the rate of x percent per year to the amount that earned interest at the rate of y percent per year was 3 to 2.
一年投资了6万,of this amount 是单利x,剩下的是单利y;总利是4080,问x
题目本身很简单,但是我就是死活看不懂“of this amount ”和“the rest ”,我认为这2个没有给出,根本无法计算啊!
求解答! |
