It s too difficult for the average expert to do it

3 * 9 = 27 is the 25 yuan charged by the boss + 2 yuan hidden by the waiter, and 3 yuan was returned to 3 people, so it should be 3 * 9 = 27 + 3 = 30

The problem lies in the fact that the person who sells the green onion himself has made a mistake and miscalculated the account. At the beginning, those who sold green onions said that 1 pound of green onions cost 1 yuan (green onions and green onions are not separated), which is equivalent to 1 yuan for green onions white + green onions = 1 yuan. Later, he said that 1 catty of green onion white 7 cents, 1 catty of green onion 3 cents, that is to say, 1 catty of green onion white + 1 catty of green onion green = 1 yuan.

In this way, that is to say, the ** of green onions has changed from 1 yuan a catty to 1 yuan and two catties, and the total value of the green onion is naturally reduced by half. Those who sell green onions should price half a catty of green onions at 7 cents (1 catty yuan), and half a catty of green onions at 3 cents (1 catty and 6 cents), so that it is reasonable.

Obviously, the snail actually only moves up 1 meter per day, but it should be noted that if it has reached the wellhead, it will not be falling, which is where this question is confusing. After figuring this out, it is clear that the snail climbed 4 meters in the first 4 days, and climbed 3 meters during the day on the 5th day, and climbed out directly, so the snail actually climbed out of the well in 5 days. But in fact, on the night of the fifth day, when the snail was about to crawl out, he accidentally came to know that he was asked, and in retaliation, the snail returned to the place where it was most familiar...

When I have nothing to do, I take a walk on the wall of the well, and I think to myself, "Don't let you know when I'm going out."

15 pcs! This topic is about recycling! First buy 3 peaches and eat for a peach, buy 2 peaches and eat in exchange for a peach, leave a peach, buy 2 peaches and eat plus the remaining one peach, you can change a peach, eat and leave a peach, and then buy 2 peaches and eat the remaining peach can be changed to another peach, and finally there is a dime left in the buy a peache, which is calculated without asking the boss to borrow 15 peaches, if you borrow you can eat 16 peaches, in short, the money should be bought separately, start to buy 3 peaches after eating and buy 2 After eating, I changed and bought 2 more I kept buying it in a loop, and every time I finished eating, I left a peach beard to make up 3 peach beards next time.

1 1 1 1 = 15 After watching for a long time, none of the answers are right! I really don't want to go, come up and publish it!

1) 27 yuan is including the waiter's money, and 27 plus 3 yuan returned is 30 yuan.

2) 1 kg of green onion white 7 cents, 1 kg of green onion leaves 3 cents, and 2 kg of green onion 1 yuan.

3) Actually climb 1 meter a day for 7 days, but also include falling at night, is 6 days.

4) One dime a peach, 1 yuan can eat 10 peaches, 10 peach hu for 3 peaches, 3 peach hu for 1 peach, a total of 14 peaches.

1.It should be 3*9 for each person - the waiter took 2 - the boss took 25

2.The sale of green onions is a total of one catty, that is, that thing is 100 catties of green onion white + 100 catties of green onion leaves = 100 catties of complete green onions, and the people who buy them only have a total of 100 catties of green onions, so they only use 50

3.It should be 7 1+3, which means that for 7 days, climb 1 meter a day, and you can climb it in one breath on the last day.

Cents for a peach then it is 1 yuan = 10 cents, in the division of 3 peaches for 1, that is.

10 peaches + 3 of them + you have one more peach + your remaining peaches are 1 peach in exchange, that is, 15 peaches.

The correct answer should be 1 yuan and 15 peaches and 2 more peaches, that is, you are adding a dime, and you can eat 17.

The difficulty of Diablo III varies from person to person, and it depends on the equipment.

You think the Expert difficulty is difficult because you are poorly equipped and you don't have a pinnacle level.

At the expert level, you have to slowly increase the difficulty, otherwise it will be a pity to die in the later stage.

Diablo is a slow game, the faster you play, the faster you don't have fun.

I just want to know if you're at full level.

You're so bored, haha, how empty you really are.
