yiT"hvgWE ai
[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)。%p,bRxT!m*u*JJ
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]-uG+a?@

[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

[color=White]分3組4隻波子秤

Group C: 9,10,11,12
Group D: 13;C.f]hQ){

Round 1vS]:BR6h
Group A vs Group Bb-p uLl:nr
如A and B一樣, 即較輕一粒在Group C or D

Round 2`.G9E:`&b
再在Group C拆成:8{&q5KExC"w
Group Ca: 9,10
Group Cb: 11,12
然後再秤, 如一樣, 即13為較輕一粒.9O!Tnr_S

如不同, 即較輕一組有一粒較輕波子在其中, !J.D1eX O6M3n&c
要再秤, Round 3, 之後便知答案..x0erW4g(`F3T

e.g. #1 假設10為較輕的一粒

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:)Wu,yP O7_0~O

13粒一定得 :agree::agree::agree:

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...6V0g_iK'Rwm
.a6kG@d)f
[color=White]先將13粒波子分為5份….姑且叫佢地做A,B,C,D及E…$o6a1MR/eNw
A,B,C,D四份都係3粒波子…..最後E果份就係1粒波子….pA6`ac n2z9N'NI]J
咁果一粒當然一定晌A,B,C,D,E果五份是但一份到….
"qz"nJ^0b-Wh'x._
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)…. dFH_he1u`
跟手磅C同D….大家亦都會係一樣….(第二次磅)…t*A5S_8et.^ V0D3f
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)…4hDpcP&P|2N:h
咁樣就證明左A=B=C=D…咁果粒當然就係E啦…..#Ru9OY5z*i!t0|&A6R
6YbON*UPp/D8|
世事當然唔會咁簡單…..如果果粒唔同既晌A/B/C/D度又點???fkS-} xeEM
假設佢晌A度…..ANW0j9?Yt5w Y
先磅A同B….A對比B會係輕d/重d…(第一次磅)…. %XA{g7S J,S
跟手磅C同D….大家都會係一樣….(第二次磅)…M#?5Q\svD
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……….

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)…QH'j5\2d9_Zv k7M

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]
