There is no problem with the first 10 bottles and 5 bottles, then divide the 5 empty bottles into 4 empty bottles and 1 empty bottle, the first 4 empty bottles are replaced by 2 bottles, and the 2 empty bottles are replaced by 1 bottle after drinking, at this time, the number of empty bottles left on hand after drinking is 2, the 2 empty bottles are replaced by 1 bottle and continue to drink, after drinking, the 1 empty bottle is replaced by 1 bottle of soda, and the empty bottle can be returned to others after drinking, so the maximum number of soda that can be drunk is: 10 5 2 1 1 1 20

A manager has 3 daughters, the age of the three daughters adds up to 13, the age of the three daughters is equal to the age of the manager himself, a subordinate already knows the age of the manager, but still can't determine the age of the manager's three daughters, at this time the manager said that only one daughter has black hair, and then the subordinate knows the age of the manager's three daughters, and asks what is the age of the three daughters? Why?

The manager has twin daughters, who are 2, 2 and 9 years old; The age of the manager is 32 years old.

It is closely related to biology. The relationship between hair color and age.

The subordinate knows the age of the manager, as long as 13 is divided into three numbers, and the product of the three numbers equals the age of the manager in a variety of possibilities.

Therefore, the reason why subordinates cannot guess the answer is: there is no additional condition, and there is no definite solution to the ternary equation, which must be converted into a binary equation.

Assuming that there are no twins among the three daughters, then the difference between the ages of the three should be greater than one value (biological common sense).

Black hair is the dominant gene, and if neither the manager nor the couple is black-haired, then the dark-haired girl is.

There is only one truth: there are no twins among the girls, but there are two girls who are the same age!

Then, solve the binary equation.

Can't do it. Because you have two empty bottles after drinking, but you actually owe the boss two bottles of soda. However, how is it possible to exchange two bottles of soda with four empty bottles?

Unless you owe the boss a dollar. If you count like the previous floors, isn't the boss begging to lose money?

The equation is: 10 1 10 bottles 10 2 5 bottles 5 2 5 bottles 5 2 bottles.

2 2 1 bottle (1+1) 2 1 bottle Borrow 1 empty bottle from the boss (1+1) 2 1 bottle.

A: Up to 40 bottles.

You can only press the door button as soon as the door closes (it won't work if the elevator is already going up) and escape from the second floor. There should be no other keys in the elevator to stop the elevator or not stop on the 3rd floor, or stop on the 3rd floor and do not open the door.

The elevator has an emergency device, a power outage or something like that.

Stay in the elevator and don't go out, keep going up.

Someone asked this question, you see if there is a good one:

Here's a similar question, and the answer is the same.

Explanation 1: That dollar is not less.

The three of them each took out ten yuan to the boss, the boss charged a total of 30 yuan, the boss took out five yuan to the spring waiter, and there was 25 yuan in his hand, the waiter was greedy for two yuan, and there were 2 in his hand, and the waiter gave one yuan to each of the three people, and the three people talked about 3 yuan, and the boss's 25 + waiter with Sensui's 2 + 3 = 30 yuan for three people.

Explanation 2: Don't be deceived by this question, in fact, the reason is very simple.

27+2, it doesn't mean anything, these two numbers can't be added together at all. We might as well think of it this way, what is 27, is the sum of 25 yuan of the actual room fee and the 2 yuan hidden by the waiter. It already contains 2, and adding 2 doesn't make sense.

Correct calculation: the actual room fee is 25 yuan, and the waiter hides 2 yuan, which is a total of 27 yuan; "The remaining 3 yuan was distributed to the three people, and each person was given 1 yuan", 27 + 3 = 30, which is the money paid by the first three people. In this way, there is no contradiction.

According to the final result, each person actually paid 90 yuan, and the three of them totaled 270 yuan, 270 = 250 (the accommodation fee charged by the boss) + 20 (the money hidden by the waiter), the two yuan of the waiter has actually been included in 270 yuan, and there is no point in using it to add 270 yuan, so there is no formula of 270 + 20, there is no loss of any money in the transaction process, and it does seem that there is 10 yuan lost on the surface, In fact, only Yu Liang was misled by the meaningless formula of 270 + 20, and the person who asked the question wanted to use the equation of 270 (accommodation fee + money hidden by the waiter) + 20 (money hidden by the waiter) = 290 (meaningless result) and 270 (accommodation fee + money hidden by the waiter) + 30 (the returned money received by the guest) = 300 yuan (the total amount of money that appeared at the beginning of the question).

Of the 20 left by the waiter, there are 10 yuan starting with theirs, and 10 yuan is the boss's.

The algorithm was wrong, and the 270 yuan paid by the three people already included the 20 yuan stolen by the waiter.

Let's start with x coconuts, and let's write x as (x+4) 4

The first man came and gave 1 to the monkey, and at this time a coconut.

x+4) 4 1=(x+4) 5, which can be divided into exactly 5 portions, and the number of coconuts in each serving is.

x+4)－5]/5=(x+4)/5－1

x+4) 5 must be an integer, so (x+4) is a multiple of 5, and after the first person takes a portion, the remaining coconut is:

4/5)×[x+4)-5]＝(4/5)×(x+4)－4

Again, the second man came, gave 1 to the monkey, and after taking a portion, the remaining coconuts numbered.

4/5)×[4/5)×(x+4)－5]

Since (4 5) (4 5) (x+4) is an integer, (x+4) should be a multiple of 5 5 25, so that five people take one point at a time, and there is exactly one left.

x+4)-5 coconuts, so (x+4) must be a multiple of 5 5 5 5 5, i.e. x+4 = 5 5

So: x=3125-4=3121

That is, there is a minimum of 3121 coconuts at the beginning.

This pile of coconuts has at least 15621

The first man gave 1 monkey, 3,124 hidden, and 12,496 remained;

The second man gave 1 to the monkey, hid 2499, and left 9996;

The third man gave 1 monkey, hid 1999, and left 7996;

The fourth man gave 1 monkey, 1599 hidden, and 6396 remained;

The fifth man gave 1 monkey, 1279 hidden, and 5116 remained;

In the end, everyone divided it into 5 portions, 1023 pieces each, 1 more, and gave it to the monkey.
