A certain store will order 25 crates of apples. The apples will be of three different varieties-McIntosh, Rome, and Winesap-and each crate will contain apples of only one variety.

我觉得这件事应该这么理解,这里求w,最小,他不是和MR比最小,而且他已经说了,W>M.R

差一点点就对了,哎!原来是要四舍五入的呀

想要Winesap数量最少,就要其他两个数量最多。其他两种苹果只有在最接近平均数时最大,所以其他两种最多是8个。W就是9个。

就是说做这道题的时候,基本的思路每个品种的箱数数量至少是一样的,多出来的一箱再拿给W这样才能符合题意??果然不能太想当然 呜呜呜呜

不是说least possible number吗?n大于等于9的话,7、8都不可能啊,有没有好心人解答一下
leon小恶魔回复414617qqin
w=9,m=8,r=8

more than。。所以不该是10吗。。

25=24/8+1 所以一个8+1 两个8,这个8+1就是最小的情况了,再往下就加起来得不到25了

答案来自Misscherry小美丽 一共25箱苹果,3个品种,每箱只能装一个品种,W品种数量比M品种多,W品种数量比R品种多,问W品种至少多少箱,用25/3=8箱余1箱,至少余下的1箱给W,W的数量才有可能比任意两个其他品种多,所以是8+1=9,其他两个品种各8箱。这是至少的情况,因为如果余的一箱给了任意其他品种,W品种必须比9大才能保证比其他两箱大,有点绕。
Alice在学习
我也以为每一个品种数量都要不一样,提醒自己不要想当然

如果说more than可以表示大于等于 那题意不应该是M≤R≤W?真的不懂给的解析是什么意思耶
浣沅九回复大大松松鼠
more than不能认为是大于等于啊,你说中文的7比6大中的“比...大”总不能理解成大于等于吧

请问More crates of W than more crates of M and more crates of W than crates of R如何能得出M≤R<W?
浣沅九回复大大松松鼠
这个就是SC中的平行结构,这句话的意思是:W比M多 and W比R多。没有说M与R的关系...gmac老头们挖的深坑啊 总是掉入想当然的陷阱

这个题错的原因是:以为每个品种的数量要不一样……
