A farmer intends to distribute his property according to the allocation

9: Let the total property be x and the number of people n

Then there is the formula x n=100n (according to the last one) --1).

100 + first and last) --2) formula.

200 + second and last) --3) formula.

3) formula - (2) formula, solution.

n=9---4).

The total property is calculated according to equations (1) and (4).

x=8100

So the total property is $8,100, and the total number of sons is 9, and then you can go in and check one by one, and each person gets $900.

The calculation is as follows: the first son divides 100 first, and then divides 10% from the remaining 8000, which is 800, so the total is 900

The second son divides 200 from 7200, and takes 10% of 7000 which is 700, so the total is also 900

The same applies below. You ask a question twice, hehe, I hope I can be selected once, hehe, don't choose me twice, so as not to be reported for cheating.

Set the old man has X yuan of property, according to the title.

100+10（x-100)%=200+

The solution is x=8100

100+10（x-100)%=900

So he had a total of (8,100,900) sons, i.e. nine.

The 2-element equation is not easy to solve).

The elderly have a property of x yuan.

Each son is equal in property, and only the first and second are equal.

100 + (x-100) * 10% = 200 + * 10% to calculate the property is 8100 yuan, and the first son is 100 + (x-100) * 10% = 900

900 for each son, there were 9 sons.

Set: There is x dollars.

100+x（1-10％）=200+

Then solve the equation.

Let his total fortune be x dollars.

x-100)*10%+100=((-200))*10%+200x=$12,100, the first son gets $1,300, a total of 9 sons.

Let's say this farmer has x sons.

Then the (x-1) son gets (x-1)*100 yuan and the 10th son of the remaining property gets x*100 yuan.

We can know that the 100x share of the xth son at this time is 90 of the remaining property (I hope you can understand this, although it is not accurate that the remaining property here refers to relative to the (x-1) son).

So 100x=100x9+(x-1)100, so x=9, this is the method of a one-dimensional equation, it's very simple!

Here's the binary hope to understand.

Assuming that each son receives x and the total property is a, then for the first son x = 100 + 10% (a-100) and the second son x = 200 + 10% (a-x-200), solve the equation to get x = 90 + 1 10 * a 11 10 * x = 180 + 1 10 * a to get a = 8100 x = 900 So 8100 900 = 9 (one) Answer: There are 9 sons.

1) Now it is not "distribution according to work", in the past, when eating a big pot of rice, it was "distribution according to work", according to your labor score, more work and more work, less work and less work, no work, at the end of the year, according to the work, so at that time it was according to work.

2) Now it is contracted land, your income is determined according to the income of your operation, and the size of your labor has nothing to do with the size of your labor, after you work hard to operate, the harvest is abundant, but your products cannot be sold, it is likely to be lost, no income. Maybe you are lucky, although the output of your product is not high, but the market is extremely high, then you may have a good return. So this is not distribution according to work.

3) Fundamentally, there is no problem of allocating the contracted land, who will allocate it to you?
