[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)。i!J*cl9SY
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]+jb-j+c*MxV aV?9ZD

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:)

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...ob1y?r9l

[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….
咁果一粒當然一定晌A,B,C,D,E果五份是但一份到….
z8mD2B`B2F+B
先假設果一粒晌E果份到…..咁就簡單….I7gf| ok5b
先磅A同B….大家都會係一樣(第一次磅)…. "N1IMk%w"hC~ ^x#Ok
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)…%{8d6|8N%|
咁樣就證明左A=B=C=D…咁果粒當然就係E啦…..
AykxH'bM!g
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)….
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…..
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……….oF Q:tHO#K
