题目
A house valued at $200,000 two years ago lost 40% of its value in the first year and a further 20% of that reduced value during the second year.
Quantity A
The current value of the house
Quantity B
$100,000
解析
将200000美元减少40%，乘以0.6即可（减少40%等同于保留60%）：
200000 × 0.6 = 120000 美元
再将120000美元减少20%，乘以0.8即可（减少20%等同于保留80%）：
120000 × 0.8 = 96000 美元
B项数值更大。
