Math problems, high IQ come from

Knowing your mistakes and not changing them is uncomfortable to look at.

Does this have anything to do with IQ?

dEach couple is counted as a group.

There are 5 groups of people in total, and because the husband and wife can also change the order.

So there is (5!/5)*2^5=24*32=768b f(2)=f(1)^2

f(3)=f(1)f(2)

f(n)=f(n-1)f(1)

f(2)/f(1)+f(3)/f(2)+.f(2009)/f(2008)

3) C first row 5 letters, hello=(A5,5)=120, there is even a l, so go out=120 2=60

In-a correct =594)d

At least 11 contain iron and calcium.

Up to 43 contain iron and calcium.

There are also 32 that contain other substances (non-iron, calcium).

Question 1: C Question 2: B Question 3: B Question 4: D

Don't blame me for my mistakes!

1 5！5 * 2 5 = 768 choose a

2 f(2) f(1)=f(1)*f(1) f(1)=f(1)f(3) f(2)=f(2)*f(1) f(2)=f(1) original formula=f(1)*2008=2008 choose b

3 5!2-1=59 has two l at 2 and hello is right, subtract 1 to choose c

4 The maximum is 43, that is, the total calcium content of iron, and the minimum is 68 + 43-100 = 11 choose d

1 choose A2 choose B

3 choose C4 choose D

Absolutely.

Can a person with a high IQ figure figure out these questions?

Then I have a high IQ.

The answer should be correct Question 1: C Question 2: I can't see Question 3: B Question 4: D

Don't blame me for my mistakes! I just did the best I could! I did my best!

According to the title: Let fx be the number represented by the xth cell (e.g., f2=7, f6=3, known) because f6+f5+f4=f5+f4+f3

So f4 + f5 + f6 = 8 + f5 + 3 = 18 so f5 = 7 to sum up this feast on the above Mori said: f1 = 8, f2 = 7, f3 = 3, f4 = 8, f5 = 7, f6 = 3

i.e. 873873.

It's not difficult to draw a multi-color (and only 4) pattern.

Rule: Sum of row values = sum of column values.

Apply the Manuscript Regularity to list the equations:

i.e. 476=? +335

Get? =476-335=141

Consider a system of column equations and solve them according to the standard method. It's cumbersome. Bury aside.

Just ask for the numerical value represented by the question mark, you don't have to pay too much attention to the details of each color, the sum of the numbers represented by all the figures is equal to the sum of the numbers in the four columns, and it should also be equal to the sum of all the rows

A circular flower bed, 6 meters in diameter, and a one-meter path is built around the periphery to find the area.

You let the worker work for you for 7 days, and the reward for the worker is a gold bar. The bars are divided into 7 connected sections, you have to give them a bar at the end of each day, if you are only allowed to break the bar twice, how do you pay your workers?

If you go to the bookstore, you can go to the bookstore and take a look at the kind of logical thinking training, which is very thick and big, it is a super platinum version, a book is more than 20, nearly 30.

Bookstores go to buy these kinds of books, there are all of them.

1.There are 3 people to stay, 30 yuan a night. The three of them each paid 10 yuan, and 30 yuan was handed over to the boss.

Later, the boss said that today's discount was only 25 yuan, and took out 5 yuan and ordered the waiter to return it to them, and the waiter secretly hid 2 yuan, and then divided the remaining 3 yuan to the three people, each of whom received 1 yuan. In this way, at the beginning, each person paid 10 yuan, and now it is returned 1 yuan, that is, 10-1 = 9, each person only spent 9 yuan, 9 yuan per person for 3 people, 3 x 9 = 27 yuan + 2 yuan hidden by the waiter = 29 yuan, and one yuan went to **??? This question caused a huge response during the interview in New Zealand.

Does anyone know the answer?

2.There was a person who went to buy green onions and asked how much is a pound of green onions The person who sold the green onions said 1 yuan and 1 catty This is 100 catties to finish 100 yuan The person who bought the green onions asked again The green onions are not sold separately The people who sold the green onions said that they sold the green onions white 7 cents and the green onions 3 cents The people who bought the green onions bought them Weighing the green onions white 50 catties The green onion green 50 7 cents is equal to 35 yuan The green onion 50 3 cents is equal to 15 yuan 35 + 15 is equal to 50 yuan The person who bought the green onion gave the green onion seller 50 yuan and left And the person who sold the green onion wondered why he wanted to sell the green onion for 100 yuan And why did the person who bought the green onion buy it for 50 yuan? Why do you say that?

Think about it and leave the answer behind.

3.There is a well 7 meters deep There is a snail climbing up from the bottom of the well, climbing 3 meters during the day and falling 2 meters at night.

4.A dime a peach, three peaches for a peach, how many peaches can you eat for 1 yuan?

5.There were twelve ping-pong balls of the same shape and size, and only one of them weighed differently from the other eleven, and it was now required to weigh it three times with a weightless scale, to find out the ball of unusual weight, and to know whether it was heavier or lighter than the other eleven.

6.A merchant rides a donkey across a 1,000-kilometre stretch of desert to sell 3,000 carrots. It is known that donkeys can carry 1,000 carrots at a time, but they have to eat one carrot for every 1 kilometer they walk. Q: What is the maximum number of carrots a merchant can sell?

A well is 12 meters deep, a small snail starts to climb from the bottom of the well, climbs 4 meters during the day, retreats 3 meters at night, and asks how many days to climb out?

A pasture is overgrown with grass, and the cattle are grazing and the grass is growing at a constant rate, and 27 cows can eat all the grass on the pasture in 6 days; It takes 9 days for 23 cows to eat all the grass in the pasture, but if 21 cows come to eat, how many days will they eat?

Please send out the title, thank you!

Can't compare. Let A be x and B be y, then x-1 4=(3 4)y If A is 1, then B is also 1, that is the same amount.

If A is 1 2, then B is 1 3, and if A is 2, then B is 7 3

Therefore, when A is less than 1, A is more than B;

When A is equal to 1, A is equal to B;

When A is greater than 1, A is smaller than B.
