A candy assortment consists of seven flavors of chocolate-covered creams packed in two-layered boxes with 27 creams in each layer. The flavors are always packed in rows so that the flavor varies with each piece in the following order: vanilla, orange, cherry, vanilla raspberry, lime, pecan, cherry, lemon. How many chocolate-covered vanilla creams are needed to pack 200 boxes of the assortment?
选项
A、600
B、1200
C、1800
D、2400
E、3600
答案
D
解析
一份包括7种口味的巧克力奶糖被装在双层盒子中,每层装27块奶糖。每行放置的奶糖块块口味不同且以如下口味顺序放置:vanilla,orange,cherry,vanilla,raspberry,lime,pecan,cherry,lemon。问200个糖果盒中需要装多少块vanilla口味的巧克力奶糖?
解:本题的正确答案是(D)。糖果盒的每行9块糖中有2块是vanilla口味,每层有27÷9=3行,每个盒子中有2层糖,那么每个盒子中vanilla口味的奶糖有2×3×2=12块,所以两个盒子有共有vanilla口味的奶糖12×200=2400块。
