Brain Teasers

[konakathy]

I thought this might be a fun thread to start. I'm always attempting to solve puzzles and answer quizzes, a little mental floss activity to keep the brain cells healthy. I'm not the best at it, but I do love a challenge and it can be fun, too. Post your brain teasers and let the games begin.

I didn't beat the clock but it was fun quiz to take. Ready. Set. Go !

Name a President for Every Applicable Letter in the Alphabet | Mental Floss (http://mentalfloss.com/article/63162/name-president-every-applicable-letter-alphabet)

I had to resort to middle initials on some of these, but I still didn't get any results for I, Y, or X. We are talking strictly about U.S. presidents here, right? If you include nicknames you could have Ike for I but then you have to pull him out of E.

... for Every Applicable Letter ...

[Cactus]

Yes, every applicable letter in the alphabet. Are you saying X or Y are not applicable letters in our alphabet? :confused:

[userque]

Yes, every applicable letter in the alphabet. Are you saying X or Y are not applicable letters in our alphabet? :confused:

LOL...they are not applicable with respect to the challenge. Also, those letters aren't included in the website for this challenge:

Name a President for Every Applicable Letter in the Alphabet | Mental Floss (http://mentalfloss.com/article/63162/name-president-every-applicable-letter-alphabet)

Can you name the presidents for every applicable letter in the alphabet in less than a minute?

Userque, thanks for posting the table with letters and Last Name fields. I didn't see that when I went to the site.

No problem Cactus.:smile:

Here is a word game challenge I have been working on this week, let's see how many can guess the correct answer. I will post the answer by tomorrow evening , or acknowledge if someone guesses correctly before then. :D

Take the names of two politicians in the news, switch the first letter of their names, read it backwards and it will name something that they are not.

​Good luck !

Here is one that was on the internet:

Albert and Bernard just became friends with Cheryl, and they want to know her birthday. Cheryl fives them a list of 10 possible dates.
May 15, May 16, May 19
June 17, June 18
July 14, July 16
August 14, August 15, August 17

Cheryl tells Albert and Bernard separately the month and the day of her birthday respectively.

Albert: "I don't know her birthday, but I know that Bernard does not know too."
Bernard: "At first I don't know her birthday, but I know now."
Albert: "Then I now know her birthday."

When is Cheryl's Birthday?

May 19.

[Cactus]

July 16

18 & 19 are unique days so it can't be in May or June.

It can't be the 14th because then Bernard wouldn't know.

Albert finally knows so it has to be July 16 because August still has 2 possibilities.

[Cactus]

Here's an old one. I took my grandson fishing and he caught his first Striper. He was so proud that after taking his picture he wanted to weigh it. Being the joker that I am, and wanting to help him with his algebra, I gave him a trick scale. He weighed the fish and the scale said it weighed 5 pounds plus half its weight. How much did the fish weigh?

If one takes the word NON-PERCEPTION and rearranges its 13 letters, name 3 things that are on the same category. It's actually pretty elemental.

Iron, Cobalt, Nickel ...

etc.

[TSP-roulette]

Getting warm, very warm. Letters in 3 things must come from NON-PERCEPTION; A, B, K, L not part of 13 letters in "Non-Perception". Close though.

Well, Neon, Copper, and Tin are three elements made of those letters. Not sure of what category they share except that they are all elements.

[konakathy]

Copper, Iron, Tin

Say Frixxxx, you sat at that table full of goodies hey? You are CORRECT!!......... Almost userque, you were at the table also.

Frixxxx wins.

[konakathy]

you are missing an E.

What am I missing? Where's the other E? I was going to post the same as userque.

OK! Duh! We didn't need to utilize all 13 letters..."must come from".

You're such a brain tease, TR!

[userque]

What's the next letter in this sequence? A,D,A,E,I,B,?

When Is Cheryl’s Birthday?
Albert and Bernard just met Cheryl. “When’s your birthday?” Albert asked Cheryl.

Cheryl thought a second and said, “I’m not going to tell you, but I’ll give you some clues.” She wrote down a list of 10 dates:
May 15, May 16, May 19
June 17, June 18
July 14, July 16
August 14, August 15, August 17
“My birthday is one of these,” she said.
Then Cheryl whispered in Albert’s ear the month — and only the month — of her birthday. To Bernard, she whispered the day, and only the day.

“Can you figure it out now?” she asked Albert.
Albert: I don’t know when your birthday is, but I know Bernard doesn’t know, either.
Bernard: I didn’t know originally, but now I do.
Albert: Well, now I know, too!
When is Cheryl’s birthday?
Originally, Mr. Kong said this was a problem inflicted on fifth-graders, leading to hand-wringing that Singapore children were way better at math than everyone else in the world and worries that Singapore children were being mentally abused with convoluted logic at a young age.
It turned out the problem actually came from a math olympiad test for math-savvy high school-age students.
How would you fare in a room full of adolescent math competitors in Singapore?
(Once you think you have figured it out — or if you don’t know where to start — here is the answer and an explanation (http://www.nytimes.com/2015/04/15/science/answer-to-the-singapore-math-problem-cheryl-birthday.html).)

[konakathy]

What's the next letter in this sequence? A,D,A,E,I,B,?

G ?

[userque]

G ?

Smart guess, but not G.

[konakathy]

Smart guess, but not G.

F ? Was I off one count?

Dang! I have to go back to work and read addresses. My brain is numb.

[userque]

F ? Was I off one count?

Dang! I have to go back to work and read addresses. My brain is numb.

"F" is correct! Can you explain why "F" is correct?

[konakathy]

"F" is correct! Can you explain why "F" is correct?

Yes, but only in my convoluted way of thinking. It was a 4/5 count.

A-D (4) back to A..A-E (5) E-I (4) start at B ... B-F (5) It might not be the correct way to figure it out, but it's my pea brain way.:laugh:

LOL...interesting. I figured you did it some "other" type of way. The intended solution:

pi to 10,000 digits (http://www.math.utah.edu/~pa/math/pi.html)
Pi~3.1415926

c.adaeibF

Where a=1, b=2, c=3, etc.


The letters in question correspond to the fractional part of Pi. "F" corresponds to "6." I left out "3" or "c" (the non-fractional part of pi) to help make this teaser "google proof."

Well done!:smile:

OMG! My brain would explode if I used that equation. I'm just simple minded. :D

I've found that many times--especially with forecasting financial markets; the simple solutions work best.:smile:

(Still amazing that you got that right the wrong way.)

[konakathy]

All of you like to eat me. I am a five lettered word. Remove the first two letters and I turn into an infamous animal.

Remove just the first letter and I become a heinous crime. Remove the first and last letter and you can groove on me.

Can you guess who am I?

There are celebrities with first names, for example "Tom Arnold", (both male first names), "Grace Kelly"; (both female first names).
Name a famous actress who goes by 3 names, all 3 names are considered MALE!. So, just to emphasize, this actress has 3 male names. Her parents were also very famous actors.

Nope, but I see where you were going!

[TSP-roulette]

10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = 2840

Answer: 2840

[Frixxxx]

10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = 2840

Answer: 2840
Winner winner chicken dinner!

[konakathy]

10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = 2840

Answer: 2840

Ok! Splain, Lucy! How did you get that answer?

[TSP-roulette]

Lucy?.. kk, Haven't seen Lucy posting 'round this forum. Wait a minute. LUUUUCCCYYYYYY?????? where are you?

[Frixxxx]

Ok! Splain, Lucy! How did you get that answer?
Follow the columns to the right of the "=" and work down

First column Fib's
Second column - even number sequence
Third column - sequential
Last column - reverse of first answer

10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = 2840

[TSP-roulette]

Ok! Splain, Lucy! How did you get that answer?




10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = 2840

Answer: 2840

Add numbers in each column, i.e first column, 0+1+1=2 - Second column double the count 2-4-6-8, Third column, single count, 1-2-3-4, - then take top numbers 0218 reverse them to become 8120, plug them to last column, so now 40x2 = 2840
