1、【daan】c。zhonggongjiexi: fangfayi，shebingfenjijiaxxiang，ze280+x=1.5×(210+180-x)，jiedex=122，daanweic。

方法二，最后甲是乙的BG真人版倍，所以甲最后的箱数是3的倍数。甲开始时有280箱，280除以3余数为1，所以丙给甲的箱数除以3余数应是2，选项中只有C符合。

2、【daan】b。zhonggongjiexi: huaxueshijidezhongliangwei(80-48.5)÷(75%-40%)=90qianke，zetongdezhongliangwei80-90×75%=12.5qianke。
