题目

a, b, and c are positive


Quantity A

(a + b)% of c

Quantity B

c% of (a + b)

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。
