Brain teaser There is a person, he will not be sad, why is he in tears 5

Because I can't even be sad. And he cried bitterly.

It must have been someone else's tears flowing down his face.

There is a song called "Your Face with Tears".

Tears don't mean sadness.

How easy the question was, he cried with joy or excitement! Haha

Let the small fish x, carp y, grass carp z, this can be a system of equations:

x+y+z=100

x/16+y+5z=100

Eliminate y, there is:

15x/64=z

Because x, y, z must be integers, hence the .

x=64，y=21，z=15

So there were 64 small fish, 21 carp, and 15 grass carp. Just 100 fish, 100 catties. And there are all of them.

In fact, mathematical problems like this are very old, and they are a very common mathematical intelligence problem.

It's easy to calculate, set a few unknowns, and then use the elimination method, and you can get the correct answer.

There were 64 small fish, 21 carp and 15 grass carp.

Is this a brain teaser? Let small fish, carp, and grass carp each have a, b, and c bars, and two equations can be listed a+b+c=100, a 16+b+5c=100, and c=15a 64, considering that a, b, and c are all integers, a=64, b=21, and c=15 can be obtained

It's not a brain teaser, it's a math problem.

But your conditions are not complete, and the total amount of money should be 100.

It can be calculated with equations, old problems.

x+y+z=100

x/16 +y+5z=100

x can only be a multiple of 16, and the two formulas are reduced to 15x 16-4z=0 to 15x=64z z to be less than 20, so that it will not exceed 100 catties, and because the common factor can no longer be mentioned, z must be a multiple of 15, so z=0 or 15, exclude 0, because each must have. So z = 15, so x = 64 and y = 21

There were 64 small fish, 15 grass carp and 21 carp.

Let there be three unknowns, and the result can only be an integer, and you can solve it.

It's so simple.

Except for the Pacific Ocean, it won't be sad,,, sad Pacific Ocean.

A pig saw a big tree in front of it, why did it hit it up?

Because it doesn't make brain teasers.

The pig crossed the road, a car 5km h, the pig was hit and killed.

2.March 30 every year.

3.He is "himself".

4.Waterfall. 5.The headache is the most.

Save lives every year.

The waterfall head hurts the most.

Because it hurt the plane.

It's cold, isn't it?

Paper airplanes, what do you hurt, let's fold one. Besides, it's the plane that is bad, how can it break your heart.

The old does not go, and the new does not come.

Because you are not human, you will not be sad.

Because you insured the plane.

The answer to this brain teaser is yourself.

Analysis] The problem is "there is a person who is born to your parents, but he is not your brother or sister", it stands to reason that as long as two people are born to the same parents, then the two will be brothers and sisters, but the title says no, then there is only one possibility, this person is himself, and he and himself must be born to the same parents, but not brothers and sisters.

It's you, neither a sibling, nor a parent, then it's just you.

It's not a sibling, it's your parents, of course.

Answer one: yourself.

Answer 2: Qi, the "qi" of anger

Myself, myself, myself.

No need to ask, it's you!

Except for yourself, or yourself.

If you're angry, please adopt it in time!

"He" is yourself.

It's not a brother or sister, it's just you.

In fact, Dad wants 5 yuan, which is equivalent to less than 1 yuan and 7 jiao for a fish, and Xiao Ming's return of 2 cents is equivalent to 1 yuan and 8 cents for a fish, so there is a difference, and this difference is the reason for the 4 cents and two cents for buying marshmallows, which is actually a non-existent problem and is used to confuse everyone.

Yuan per person, Xiao Ming spent Yuan and gave his father 5 Yuan, a total of that's it, there is no 2 cents, don't faint everyone!

Or put it this way: a total of 6 yuan, Xiao Ming spent 4 cents, returned 6 cents to buy fish, gave his father 5 yuan, and it's over.

Everyone spent yuan to buy a total of 5 yuan 4 plus 2 cents for each person to return back, which is 6 cents. Multiplying 3 equals adding 6 cents, is it a total of 6 yuan, or Xiao Ming's father took 5 yuan, Xiao Ming spent 4 cents, plus 6 cents in reverse.

Don't be deceived by the title, in fact, after Xiao Ming sent out the money, Xiao Ming got 4 cents, and his father got 5 yuan, which is just equal to 3*, as for Xiao Ming, he hasn't sent out the money yet, so it can't be confused.

5 yuan and 4 cents is sold for yuan per person.

5 yuan and 6 cents is the balance of Xiao Ming who sells it for 6 yuan at 2 yuan per person and spends 4 cents.

The actual is not comparable with 5 yuan and 4 cents.

Xiao Ming spent 4 cents, returned 6 cents to buy fish, and gave his father 5 yuan, a total of 6 yuan.

There is no matter of 2 hairs.

This is how the question should be viewed. Each person spent 1 yuan and 8 cents to buy three fish. Total: 5 yuan and 4 cents. Dad got 5 yuan. Xiao Ming got 4 cents.

There was a man who bought two fish!! So he only reversed 4 cents.

This question is confusing to everyone, and the two can't be counted together.
