选项
A.The quantity in Column A is greater.
B.The quantity in Column B is greater.
C.The two quantities are equal.
D.The relationship cannot be determined from the information given.
解析
对于两个正数,**M% of N = N% of M** 恒成立。本题中,(a+b) 的形式看似复杂,但该原理依然适用。从代数角度分析:
A项:(a+b)/100 × c
B项:c/100 × (a+b)
两项均可化简为:{(a+b) × c}/100,因此二者数值相等。
