小楷跟小治兩兄弟各帶了 60 顆新鮮雞蛋到市場賣,389Please respect copyright.PENANAVyHWANpDK5
小楷要賣 3 顆 5 元,小治要賣 2 顆 5 元;389Please respect copyright.PENANACRiVU1tRbD
他們正在準備擺攤的時候想到,兩個人分開賣會互相搶生意,389Please respect copyright.PENANA0AKUkCuydE
所以就改把兩個人的雞蛋一起賣,389Please respect copyright.PENANA4EPiLMj64R
他們都想用自己原來的價格, 3 顆 5 元跟 2 顆 5 元合起來就是 5 顆 10 元,389Please respect copyright.PENANAMKgyzHIHm9
就這樣把 120 顆雞蛋都賣光了,賣得 120 / 5 * 10 = 240 元;389Please respect copyright.PENANAFlFos3HEg9
但是等他們回家的時候發現,389Please respect copyright.PENANAPcQSx9S9AW
小楷要分 60 / 3 * 5 = 100 元,小治要分 60 / 2 * 5 = 150 元,389Please respect copyright.PENANAuKNYU97vVO
但錢卻不夠分,到底是哪裡出錯了呢?389Please respect copyright.PENANAL5MWD4KDtn
