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:gg$?'m{v4cS h

[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)。
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]X/rl VG8X%x
(M'?.{#u_F!s Q ^
[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e7^v|'Y)X;I8|5I/t

[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

[color=White]分3組4隻波子秤

Group A: 1,2,3,4
Group B: 5,6,7,8
Group C: 9,10,11,12
Group D: 13

Round 1
Group A vs Group B
如A and B一樣, 即較輕一粒在Group C or DaL }c+[Y@o%{"L8\

Round 2
再在Group C拆成:
Group Ca: 9,10$sW2V,TC{
Group Cb: 11,122G%w@^sd Wu5J
然後再秤, 如一樣, 即13為較輕一粒.
9W/Bv:Mo d
如不同, 即較輕一組有一粒較輕波子在其中, 5~mIW6x.M y
要再秤, Round 3, 之後便知答案.

e.g. #1 假設10為較輕的一粒
Round 1
1,2,3,4 vs 5,6,7,8 = equal

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:)_#{-lw2~&[ Wk{

吾知輕左定重左喎.......冇得咁假設 ---> 『一早知边粒輕左/重左』使問由''已知的假設答案''出發,又点會推算出岩答案;););)

冇勇氣面對你...不過至少有勇氣答你既問題.....我答完覺得仲係有d唔妥......不過我好相信我呢個應該好接近答案..........去片...

[color=White]先將13粒波子分為5份….姑且叫佢地做A,B,C,D及E…
A,B,C,D四份都係3粒波子…..最後E果份就係1粒波子….CRa EV;V
咁果一粒當然一定晌A,B,C,D,E果五份是但一份到….

先假設果一粒晌E果份到…..咁就簡單….
先磅A同B….大家都會係一樣(第一次磅)…. *I1QL(mi\3B*pr
跟手磅C同D….大家亦都會係一樣….(第二次磅)…7x'M"C&g0g8w~x*^x
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)…
咁樣就證明左A=B=C=D…咁果粒當然就係E啦…..w9mh,U5B,X} q ^3~
%C"QmV{Svp
世事當然唔會咁簡單…..如果果粒唔同既晌A/B/C/D度又點??? E3rb)b(B7q)_
假設佢晌A度…..
先磅A同B….A對比B會係輕d/重d…(第一次磅)….
跟手磅C同D….大家都會係一樣….(第二次磅)…
係咁既情形下即係果粒唔同重量既一定晌A入面…..最後再攞A入面是但兩粒黎磅…(第三次磅)…如果係一樣既…..咁剩低冇磅果粒當然就係唔同果粒啦…..k)U^4Fz+W
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……….DX6rc w x*e6PIf1V
f!MY&`-{&s"rjPwr
而晌咁既情形下E無論點當然都唔駛磅啦…..(佢一定唔係唔同果粒)…
M)H)I+a^N4j#G
如果果粒唔同既晌B/C/D度都係用一樣原理咁抽佢出黎……[/color]
