[機經] 機經密碼...
有人知道這個月的機經密碼嗎..Q_Q
另外問一題數學
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%
我的算法是
X * 1.10=X * 1.01*(1+K%)
算出K得8.9%
是我對於題目的理解有錯嗎?
感謝各位
