There are three boxes labelled as Red Balls, Black Balls and Red and Black Balls. Each one of the box is labelled incorrectly. You have just one chance to pick up from any box and then label the boxes correctly.
How will you do it?
Pick up from the box that is labelled as Red and Black Balls. Since they are labelled incorrectly, it should have either Red Balls only or Black Balls only.
Suppose you get a Red Ball, then you will be sure that this box has Red Balls only and you can label it that. Now the box that has been labelled as Black cannot have Black balls as all were labelled incorrectly. Also, we know that we have found the Red Balls box. Thus it must be the box with Red and Black Balls. Now the only box that remains is the one labelled as Red Balls. You can label it as Black Balls now.

There are three identical triplets sisters. Demi is the oldest of them all and she always speaks truth. Diana is the next one who is a liar always. Drew, the youngest of them all speaks both truth and lies randomly.
On a rainy day, a family friend Victor visited them. Since there were starkly identical, he was not able to recognize them. Thus to clarify, he asked one question to each one of them.
He started with the one standing on the left and asked, 'Which sister is in the middle of you three?' She answered, 'That’s Demi.'
Then, he asked the one standing in the middle, 'What is your name?' She answered, 'I am Drew.'
Finally he asked the one standing on the right, 'Who is standing in the middle?' She answered, 'She is Diana.'
Victor was left baffled. He asked the questions three times and received different answers every time.
Can you tell who was who?
The first girl cannot be Demi as that would make the first one liar. For the same reason, Demi cannot be the second one as well. Therefore, the third one is Demi for sure. This further suggests that the middle one is Diana and the one on the left is Drew.

#1489 - Easy Logical Question
Three friends named Mr. Black, Mr. Yellow and Mr. Green enter a pub on a weekend night. They are wearing either a Black, Yellow or Green shirt.
Mr. Yellow says to them, 'Did you notice that we all are wearing different color shirts than our names?'
To this, the man who was wearing the Green shirt said. 'Wow, thats right.'
Can you identify who is wearing which color shirt ?
The answer is right in front of you. Since all are wearing different color shirts from their names, we know that Mr. Yellow is either wearing a Black or a Green shirt. But through the two statements, we already know that Green shirt is worn by somebody other than Mr. Yellow. Through this we can deduce that Mr. Yellow is wearing a Black shirt.
Now Mr. Green is definitely not wearing a Green shirt and since Black shirt is already worn by Mr. Yellow, he must be wearing a Yellow shirt.
Now we have one person left and one color left. Thus, Mr. Black must be wearing a Green shirt.
