题目的解释是一年？我看题目表达的意思时间跨度是10年啊

问题如下：

From the beginning to the ending years of a decade, the annual value of final goods and services for country X increased from €100 billion to €300 billion. Over that time period, the GDP deflator increased from 111 to 200. Over the decade, real GDP for country X increased by approximately:

选项：

A.

50%.

B.

67%.

C.

200%.

解释：

B is correct.

Real GDP in the first year was €100 billion/1.11 = €90 and in the last year it was €300 billion/2.00 = €150. Thus, (€150 – €90)/€90 = 0.67 or 67%.

考点： GDP deflator

解析：运用 GDP deflator 反解除一年前后的真实GDP数值，

一年前：€100 billion/1.11 = €90

一年后：€300 billion/2.00 = €150

在进一步求得真实GDP的增长率，(€150 – €90)/€90 = 0.67 or 67%.

或者

NOMINA2/NOMINAL1=3/1

DEFLATOR2/DFLATOR1=(NOMINAL2/NOMINAL1)×(REAL1/REAL2)

200/113=REAL1/RELA2

REAL2=REAL1×1.665

所以，INCREASE=66.5%

嗨，从没放弃的小努力你好：


题目的解释是一年？

题目的含义是一年。我们看到From the beginning to the ending years of a decade, 这个含义是，从年头到年尾的这段时间。


我看题目表达的意思时间跨度是10年啊

可能是decade这个多义词的关系。

decade可以表示十年，也可以表示某一段时期。

在本题中，decade是指从年头到年尾的时期（From the beginning to the ending years of a decade）
