问题 成本0.25元的纽扣1200个,如果按40%的利润定价出售,当卖出80%后,剩下的纽扣降价出售,结果获得的利润是预定的86%,剩下纽扣的出售价格是原定价的百分之几?( ) A. 75% B. 76% C. 80% D. 82%
选项
答案 C
解析 0.25X40%X1200X80%=96(元)......卖出80%后的获利 0. 25X40%X1200X86% = 103. 2(元)......按86%卖获利 (103. 2-96)/(1200X20%) = 0. 03(元)......剩下的每个纽扣应获利 故得(0. 25 + 0. 03) /[0. 25X(1+ 40%)]=80%。
