Re: [其他] 南二中104教甄數學題Q1
※ 引述《ijustsleep (明天才做的是傻瓜>"<)》之銘言:
: A、B兩男士好奇地詢問C女士的年齡,C女士列出11個可能的答案:
: 35、36、38
: 42、45、46
: 51、55、57
: 61、62
: 接著C女士將她年齡的十位數告訴A男士,將她年齡的個位數告訴B男士。
: A男士說:「我不知道C的年齡,但我想B也不知道。」
表示A所知的那個十位數,同組中每個個位數字都出現2次以上
(例如: 如果B知道的是8,那B就應該知道是38)
因此A知道的應該是4或6
: B男士說:「我原本也不知道C的年齡,但現在知道了。」
B推論出十位數是4或6時,就可以推測出年齡
表示應該是45、46、61
: A男士說:「哦,娜現在我也知道了。」
A知道是45、46、61後也可以推論出來,表示是61
: 請問C女是的年齡是______歲。
: 是朋友傳在群組裡的 他猜61 我猜45
: 不知道這題怎麼算然後答案多少
: 剛剛我去看了學校網頁只有公布題目沒有答案
: 麻煩各位高手了 謝謝
