### Brain Teasers

# Eating, Laughing, Thinking, and Yawning

Math
Math brain teasers require computations to solve.

Twice the number of people eating equals half of the people who are laughing; if twenty people are thinking, and all of the people thinking are also all of the people laughing... and a quarter of the people laughing are also yawning, then how many people are yawning? How many people are eating?

### Hint

It is a low level of math, nothing too hard. It just takes some thinking.### Answer

E= eatingL= laughing

T= thinking

Y= yawning

E= 0.25L

20= T

20= L

E= 0.25 x 20

E= 5

Y= 0.25 x 20

Y= 5

There are five people eating and five people yawning.

Right over my head...lol

Sure, it was easy, but it was also well written - good job, NoQuestion

good boy

im a gurl!

awsome!

Good Lord, some one must have given me a brain transplant. This is the second math teaser I have gotten the asnwer to today. Thanks for making me feel so smart.

Nice and easy, Just the way i like 'em

the trick is to keep only one variable- and use coefficients to represent other groups

ok... i dont even really like math, but i guess this one just popped into my head

fun teaser .. thought it was pretty easy. just solve for one answer at a time.

that was easy but written real well..

Good one, I like this kind, a math teaser where the real problem to solve is the language!

2 thumbs up!

2 thumbs up!

Good Job! Very interesting. I love making equations...that I know my classmates probably wouldn't be able to solve.

Not much of a teaser, nor much of a math problem. Obfuscation does not make a teaser. Just following the problem meant I already had the answer when I finished reading the question.
