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%
期初和期末的deflator除的base year都是什么时候呢，想不明白。还是他们两个的基期是一个啊
