推理大挑戰(第四關)

[color=Teal]相信e條題目都有吾少人玩過,所以今次一於改難些少.....由12粒波子变成13 粒波子......不過對於識玩既朋友,應該都屬大同小異既啫[/color]:lol::lol:uu;OW?f

[color=Blue]『有 13 粒波子，有 12粒是重量相同的，有 1 粒是重量不同的 (沒有列明是輕了 / 重了)。:DSLu!}{^$C
現准許使用 3 次天秤。請解釋怎樣才能找出 13 粒內那 1 粒重量不相等 (即是重了 / 輕了) 的波子呢？』[/color]y$j:Zx(PT(L{/}dZ
xjjm]Vkb
[color=Red]注意: [/color]

[color=Red]1.[/color] 回答題目時,波子的名稱代號請用使用 1,2,3,.......至13 等數目代表, 即1 代表1號波子 , 13 代表13號波子.....以方便查證L([)dZLt

[color=Red]2. [/color]請回答題目的朋友使用'' 反白功能 '' (即係將D字既颜色改為白色,白色颜色在黑色颜色上一行,透明的呢)穩藏回答答案,費事比其他人抄 , hide 字要連埋 , 內容 = 答案

Group A vs Group B([Gs4DJTUS:x Rg9x
如A and B一樣, 即較輕一粒在Group C or D

Round 2!~D+[o,T9n1[
再在Group C拆成:R)dZAQoW
Group Ca: 9,10
Group Cb: 11,12
然後再秤, 如一樣, 即13為較輕一粒.

如不同, 即較輕一組有一粒較輕波子在其中, 2k P![vn#s

你又吾知粒波子輕D定重D ..... 咁点解第三步只磅4-6 吾磅1-3 . 如果個波子係輕D ,咁4-6 就一定一樣咁重 :naughty::naughty:

如果將個答案攞去做實驗.......最後真係會知边粒波子輕左或重左.......不過係文字上,輕左或重左都冇乜所謂(又比左Tips :lol:)

先假設果一粒晌E果份到…..咁就簡單….e1u,f^9QWs
先磅A同B….大家都會係一樣(第一次磅)…. !_~G;\!ne Z S
跟手磅C同D….大家亦都會係一樣….(第二次磅)…
最後再攞A或B同C或D磅(即A vs C/ A vs D/ B vs C/ B vs D/是但一個都冇所謂)….大家亦都會係一樣….(第三次磅)… ~g7z/r7`1ZT#H
咁樣就證明左A=B=C=D…咁果粒當然就係E啦…..

如果磅出黎係唔同既….咁就要睇番當初第一次磅既時候….A同B比較時究竟係輕左定重左…..如果係A重d既話…即係話果粒唔同既係重d既….咁晌第三次磅既時候重d果粒就係唔同果粒啦………. 如果當初係A輕d既話…即係話果粒唔同既係輕d既…咁晌第三次磅既時候輕d果粒就係唔同果粒啦……….
