题目
An item’s price was discounted by 16%. Later, the discounted price was increased by 16%.
Quantity B
The price after the discount and increase
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
题目未给出具体数值,因此选取一个便于计算的数。由于这是百分比问题,我们设原价为100美元。此时A项的值为100美元。
数值减少16%,等价于取原数的(100-16)% = 84%:即 \(0.84 \times 100 = 84\) 美元。
将该数值增加16%,即取它的116%,或乘以1.16:\(1.16 \times 84 = 97.44\) 美元。
因此,A项的值更大。
