[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:"YJ(Ev1_`c;@ f
i1|E5o6AH J,_
[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]

[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

Round 2
再在Group C拆成:o-|/d&t0dGZ3{J
Group Ca: 9,10

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,
要再秤, Round 3, 之後便知答案.

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:)

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….B?`7R3E
咁果一粒當然一定晌A,B,C,D,E果五份是但一份到….OPQ+u,W7{-UF8Z

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)….
跟手磅C同D….大家亦都會係一樣….(第二次磅)…)luzC(M%}.@
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…..

世事當然唔會咁簡單…..如果果粒唔同既晌A/B/C/D度又點???
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)…. Enb^| E.]dY
跟手磅C同D….大家都會係一樣….(第二次磅)…TkP'l/D
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…..
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……….eagL].v
wTM R-};V/f
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)…

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]
