DS：一个 z 产品的 error rate=100|e-a|/a, e is estimated value while a is actual value, is the total revenue’s error rate at least 10%(好像是) greater than z product’s revenue. The error rates of Total revenue and z product’s revenue are both less than 10%.(大致是这些条 件，这题挺难的我也不确定答案) 条件 1：z product’s estimated value=total revenue’s estimated value* 25% 条件 2：z product’s estimated value=16000
