The social order in a certain country is not good. One store (1/3) was stolen by customers, and (1/4) was taken home by employees. Gross profit. May I ask how many times the purchase price of the items in this store is sold?
某国家的社会秩序不好，有一家商店(1/3)被顾客偷窃，有(1/4)被员工摸回家，剩下的物品全部售出，结果这家商店竟然还有20%的毛利润．请问这家商店的物品是以进货价多少倍售出？
