- Suppose i use the coffee machine then the other two will be probably tea and tea/coffee but as there labels are wrong therefore we can easily tell that which one is which as the tea machine would b labelled as coffee or tea/coffee and i hv used the coffee therefore 2nd will be identified as tea hence the third will be tea/coffee

- take the one labeled either. Use that machine. if it produces coffee then its acoffee machine if it produces tea then its a tea machine since the label is wrong it cant be either one. so we get one. now in the remaining two. if we get tea from "either" then the machine labeled tea cannot contain tea so it can be either "coffee" or "either" and since another contains "coffee" which cant be "coffee" so it must be "either" labeled machine and the one labeled "tea" must be "coffee" producing machine

- We have to use machine 3.If it gives coffee,then machine 1 gives tea or coffee and
machine2 obviously gives coffee. - 10 years agoHelpfull: Yes(4) No(2)
- take the one labelled tea. and use it repeatedly. since it is labelled wrong. it must give coffee for sure. but if it gives tea as well then it is a tea/coffee machine. now we have two machines left.
case 1: the first machine was a coffee machine. hence the one labelled coffee must give tea or tea/coffee. but the third one is wrongly labelled tea/coffee. hence the third will give just tea and the second one will give tea/coffee.
case 2: the first machine was a tea/coffee machine. the one labelled tea/coffee will be either just tea or just coffee. but the other labelled coffee is labelled wrong. hence the one labelled tea/coffee will actually give coffee and the one labelled coffee will give tea. - 10 years agoHelpfull: Yes(4) No(0)

- suppose i have choosed the tea labelled machine then the other two labels will be probably coffee and tea/coffee. As i choosed coffee labeled machine that would be either tea or tea/coffee machine. If we check it as coffee machine then in the remaining two machines the one with tea/coffee label is tea machine and one with tea labeled machine is tea/coffee machine.

- first use the machine labeled either tea or coffee so that it reveals the answer.how means all the machines are labeled wrongly so that machine labeled either coffee or tea should contain either tea or coffee..if it contains tea then the machine labeled coffee will contain either coffee or tea and the machine labeled tea will contain only coffee

they are 10

- I will use the machine with the label as Random (either tea or coffee), if coffee is poured, then that is the Coffee machine.
Reason: As the labels are wrong, it cannot be Random and it also cannot be tea because then coffee was poured.
Next the machine with label Tea will be Random.
Reason: It cannot be coffee (already stated). It cannot be Tea as all the labels are wrong.
The machine left will be of Tea. - 9 years agoHelpfull: Yes(0) No(0)
