请教GWD24-18

The annual interest rate earned by an investment increased by 10 percent from last year to this year. If the annual interest rate earned by the investment this year was 1 percent, what was the annual interest rate last year?

A. 1%   B. 1.1%  C. 9.1%  D. 10%   E. 10.8%

参考答案C

是不是题目错了啊?我怎么觉得答案应该是0.91%呢?取近似值应该是A了.

设要求值为X

(1+10%)X=1%  ==>X=0.0091

大家快帮我看一下吧.

估计题目有问题吧,第二个应该是10%.
