There is a question, please help me with a high IQ

The money that the waiter hid should not be added to the money they paid. Rather, they are out and the boss discount is added together!

It should be: the boss gave them a discount of 5 yuan, and the waiter hid 2 yuan, which is equivalent to only giving them a discount of 3 yuan.

Coupled with the 27 yuan they offered, it was just 30 yuan.

To put it another way: now money: 25 yuan at the boss's.

$2 waiter there.

$3 at the guest's place.

25+3+2 is exactly 30!

This is not $9 per person.

It's that everyone spent 10 yuan to get it back, isn't this a double count.

You can calculate one like this is a total out of 30

One is a total of 3

Passenger contribution = 30-3 = 27

The innkeeper was 25

The waiter is 2

The innkeeper and waiter get money = 25 + 2 = 27

Isn't it just equal?

Even in the hands of the three guests, they didn't come up with 30 yuan, they only took 27 yuan, and if it was 30 yuan for the overnight stay, plus the waiter's was only 29 yuan, they had to pay for each of them.

So that one dollar is in the hands of 3 guests.

Instead of taking out 30 yuan, they took out 27 yuan. 27 yuan has to be distributed, you know how to distribute it, right?

How do you think that different calculation methods can have different results?

It's too easy, it's at the waiter's.

1. The old man took the dog, the old man returned, and the dog stayed;

At this time, there are fathers, sons A, sons B, mothers, daughters A, daughters B, and old men; Across the river: Dogs.

2. The old man took his son A, the old man returned with his dog, and his son A stayed;

At this time, there are fathers, sons B, mothers, daughters A, daughters B, old men, dogs; Across the river: Son A

3. The father took his son B, the father returned, and the son B stayed;

At this time, there were fathers, mothers, attendants of daughter A, daughter B, old man, dog; Across the river: Son B, Son A

4. Dad and mom have passed, mom has returned, and dad has stayed;

At this time, there are mothers, daughters A, daughters B, old people, and dogs; Across the river: Dad, Son B, Son A

5. The old man took the dog over, and the father returned;

At this time, there are fathers, mothers, daughters A, and daughters B; On the other side of the river: Son B, Son A, old man, dog.

6. Mom, dad passed, mom replied.

At this time, there are mothers, daughters A, and daughters B; Across the river: Dad, Son B, Son A, Old Man, Dog.

7. The mother took her daughter A, and the old man and dog returned.

At this time there were old men, dogs, and daughter B; On the other side of the river: Mom, Daughter A, Dad, Son B, Son A

8. The old man took his daughter B, and the old man returned.

At this time, there are old people and dogs on this side of the river; On the other side of the river: Mom, Daughter A, Daughter B, Dad, Son B, Son A

9. The old man took the dog.

The question is too simple. Don't be fooled. Since it's a bridge crossing, let's just cross the bridge together.

It can carry two people, so does a dog count as a person?

Can there be two people and one dog?

There are pictures on the advertising paper, and the answers on the Internet are so terrifying.

In the summer, people are hot and swollen, gaining weight and being overweight.

Climb 3 meters during the day and drop 2 meters at night.

Starting from the day, 0+3=3 during the day on the first day, and 3-2=1 at night

The next day 1+3=4 during the day and 4-2=2 at night

On the third day, 2+3=5 during the day and 5-2=3 at night

It is equivalent to climbing 1 meter a day, and it takes 7 1 = 7 days.

If you start at night, the first day 0-1=-1

The next day during the day -1+3=2

Late 3-2=1

The result is 1 on the third day of white 1 + 3 = 4

Late 5-2=3

That is, climb 1 meter every day, and 7 meters must climb for 7 days, but the next day it starts to climb, so it takes 8 days to climb out.

For five days, because the first four days were 3 meters climbed during the day and 2 meters fell at night, which is equivalent to climbing 1 meter in 1 day.

But on the fifth day, I climbed 3 meters during the day and then climbed out, so it was five days.

Five days, on the fourth night, I climbed four meters, and on the fifth day, I reached seven meters, and I came out.

In fact, the result is the same if the cup is not filled with water, the ice cube will absorb heat during the melting process, and condensation will be produced on the outer wall of the cup, which should be known if you have drunk ice drinks in summer.

According to the law of buoyancy, the floating object makes the page rise, and the weight of the rising liquid is equal to the weight of the floating object, and the same mass of ice is solid water, so the amount of water contained in the rising liquid level is equal to the amount of water contained in the rising liquid level.

Not necessarily, the density of ice and water varies with temperature. When the ice melts, the volume of water may or may become larger, and it may also be affected by the difference from room temperature, and the result should be uncertain.

Based on this, the killer will not succeed.
