The question of natural talent, these questions seek genius

A1· Actually, this question is misleading.

The waiter's 2 fast was originally 27 fast inside, how can you add it again.

It should be the 25+ 2 in the hands of the waiter taken away by the boss + the 1 yuan in the hands of the three people who are returned.

Answer 2: Is the boss Ha's 50 catties of green onions white + 50 catties of green onions = 50 nearly green onions? ?

Could it be that 50 catties of apples + 50 catties of pears = 50 catties of fruits??

Answer 3· 5 days to be accurate (a little more than 4 days) Climb 3 meters during the day and go down 2 meters at night is equivalent to climbing 1 meter a day, climbing 4 meters in 4 days, 5 days climb 3 meters first, and then you reach the top, and you don't fall down, so it goes up every night in less than 5 days.

Answer: 4.15 It's actually a brain teaser Buy 10 peaches for 1 yuan After eating, you can change the remaining 10 peaches for 3 peaches and leave 1 hu After eating these 3 peaches, there are 4 hu left, and after eating another peach, there are 2 hu left, borrow a hu from the boss, you can change another peach, and give the hu to the boss after eating.

So it's 10+3+1+1=15

1.First of all, the 9 yuan spent per person has included the 2 yuan hidden by the waiter (that is, ***25 yuan + 2 yuan hidden by the waiter = 27 yuan = 3 * 9 yuan), therefore, when calculating the composition of the 30 yuan, the 2 yuan hidden by the waiter should not be counted, but the 1 yuan returned to each person should be added. Namely:

3 * 9 + 3 * 1 = 30 yuan is just right!

2.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.

The sky crawled out. Dollar = 10 peaches After eating 10 peaches 10 peaches = 3 peaches + 1 peaches After eating 3 peaches = 1 peach Finally: 10 + 3 + 1 = 14 peaches plus 2 peaches.

Eat 15 peaches, snails crawl out in 5 days, because 7 plus 3 equals 10, so the man bought 2 yuan of green onions for 1 yuan.

The first 5 days Many people don't think about this question and say it's seven days. It works in a very simple way.

On the first day, the snail climbs 3 meters and drops 2 meters, then the first luck type day is 1 meter, the 4th day is 4 meters, the fifth day climbs 3 meters, it is 4 + 3 = 7 to the top, you can draw it yourself, it's very simple.

The first line of Yu 2 15 peaches column formula 10 + 10 (3-1) = 10 + 10 2 = 10 + 5 = 15 (pieces) Ideas: The first time I bought 10 peaches and ate 9 for 3, now 4 and then 3, now I eat 14 with two in my hand, so where is the other peach? I only ate 14 and there are 2 cores left in my hand, and I can't change it, so I'm going to move the gear, and I'm going to have a core on credit first, isn't it 3?

Change a peach and return the pit to him after eating.

Problem 1: The snail can climb to the wellhead in 5 days (it climbs 3 meters during the day and drops 2 meters at night. He said that he could only climb 1 meter a day, 4 meters in 4 days, and on the fifth day, he just climbed 3 meters to the wellhead).

Problem 2: You can eat 15 without credit at all. Buy 10 peaches for a dollar, eat 3 peaches first, exchange peach pits for a peach, eat two peaches, add the peaches that were changed in front of you and together, and then go to change to a Min and so on...

It's a little complicated, but you can draw a picture and look at it, and it's very simple.

One day, two days, three days, four days, five days.

2.Buy 10 Senqing peaches first, and have 10 nuclear peaches for three. I ate 13 peaches, and I left 1 peache, but I can eat 13 peaches at this age.

Three-ninth, two-sixth, four-twelve. The second is nine-thirds, six-two, and twelve-quarters.

It's simple, nothing complicated.
