Discussion Overview

The thread presents a series of brain teasers that challenge participants to answer questions quickly, focusing on logic and lateral thinking. The questions include scenarios involving races, mathematical calculations, and social interactions with a mute and a blind person. The discussion explores various interpretations and responses to these teasers.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • Some participants suggest that overtaking the second person in a race places you in second position, while others question the phrasing of the question.
  • Responses to the second question vary, with some asserting that overtaking the last person is not possible unless in a circular track, while others claim it could mean being in any position.
  • Mathematical responses to the addition problem yield different results, with some participants stating 4100 and others 5000, indicating confusion over the trick nature of the question.
  • For the question about Mary's fifth daughter, many participants correctly identify "Mary," while others mistakenly suggest names like "Nunu."
  • In response to the bonus question, participants propose various ways the blind man could express his need for sunglasses, with some suggesting he could simply ask verbally.

Areas of Agreement / Disagreement

There is no clear consensus on the answers to the brain teasers, as participants present multiple interpretations and responses, leading to a mix of agreement and disagreement on the logic behind the questions.

Contextual Notes

Some participants express uncertainty about the phrasing of the questions, particularly regarding the implications of overtaking positions in a race. Additionally, there are references to the trick nature of the math question, which may lead to different interpretations of the expected answer.

First Question:
You're participating in a race. You overtake the scond person. What position are you in?
Second Question:(Don't take as much time as you took for the first question)
If you overtake the last person, then you are...?
Third Question:(very tricky math! Note: This must be done in your head only. You're not allowed to use paper and pencil or a calculator)
Take 1000 and add 40 to it. Now add another 1000. Now add 30. Add another 1000. Now add 20. Now add another 1000 Now add 10.
Fourth Question:
Mary's father has five daughter: 1.Nana 2.Nene 3. Nini 4. Nono.
What's the name f the fifth daughter?
The Bonus round:
There is a mute person who wants to buy a toothbrush. By imitating the action of brushing one's teeth he successfully expresses himself to the shopkeeper and the purchase is done.
Now if there's a blind man who wishes to buy a pair of sunglasses, how should he express himself?

1. Second position
2. First position if its a multiple lap race, otherwise you can't overtake the last person.
3. 4100
4. Nunu
5. He's blind he doesn't need sunglasses! But he can just say it out loud.

So number 4 got me :P
And I just realized for number 2: It could be any position from first to second last

You lapped them, on a circular track; that's why I thought you would have to be first, because if you overtake the last person (which indicates the position they held before you passed them), then that means either you had to be last and now they are last or you lapped them. Seems that the wording indicates what I said.
Mmmmm, I think that's the only way, and you have the answer.

1000+40+1000+30+1000+20+1000=4090

4090 + 10 = 4100

I originally paid no attention to the first part of the question "mary's father" and just looked at the pattern of names. :rolleyes: It wasn't until I reread it later that I caught the obvious. :frown:
At least I can count. :biggrin:
The correct title of the quiz should be "how well do you pay attention?" :wink:
I'd white out paid no attention to the first part of the question "mary's father" and.
