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.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

the rest 是指什么呢？

看不懂，请帮忙解释谢谢

题目表述有问题！感觉应该是60，000分两部分存：一部分年利率x,另一部分y

答案应该是c吧

The rest的意思是“剩下的”部分。现在一共投资$60000，这笔钱分两部分产生利息，一部分的利率是x%，剩下部分的利率是y%。已知总利息是$4080，题目问利率能否被求出？

题目描述有问题！ But之后漏掉了some/part
