翻译一道数学题.

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.

Answer 1

一笔总额60000美元的投资，其中一部分的年投资回报率是x，余下部分的年投资回报率是y。如果一年后总的投资回报额是4080美元，问x的值是多少？
条件：(1) x = (3/4) y
(2)两笔投资额回报的比例是3:2

Answer 2

总共有60,000美元投资的一年。但是这个金额为每年获得x %的速度,其余每年获得每年的y百分之。如果由60,000美元的利息,那一年因4,080美元的价值,是什么呢?
(1)x =(3 / 4)
(2)量之比,获得利息的x %的数量每年挣利息的y百分之是3比2。

Answer 3

有一笔钱，其总额为60000美元，投资一年。其中一部分钱的投资回报率为X%/年，剩余部分的投资回报率为Y%/年.如果那年的投资回报额为4080美元，求X的值是多少？
（1）X=（3/4）Y
（2）投资回报率为X%/年的那部分资金与投资回报率为Y%/年的那部分资金的比是3：2
