题目

A retailer sold toys at a regular selling price of 25% greater than the retailer’s cost to buy the toys. If the retailer reduces the regular selling price by 80%, what is then the loss on each toy sold as a percent of the retailer’s cost?

选项

25%

30%

40%

75%

80%

解析

对于只涉及百分比且无具体数值的问题，几乎总是可以用 100 作为起始数值来计算。假设零售商以 100 美元的价格购入每件玩具，因此其常规售价为 125 美元。将常规售价下调 80% 后，价格降至 25 美元。每件玩具的亏损占零售商成本的百分比为： (100−25)/100×100=75因此，选项 D 正确
