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:)

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...

[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….

先假設果一粒晌E果份到…..咁就簡單….e4D8fRgB
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)…@b+VBCR}b
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…..
6V8kjMsHv
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…..;mj@:?a2Zts X
先磅A同B….A對比B會係輕d/重d…(第一次磅)…. @l z6GtG'bO+^f
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…..$E e'a!o$oM3lH0p
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……….
qS)\5B+{
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)….u,M'E?ytn
_d"c;Y Z
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]
