There are 100 pears, apples, oranges and persimmons. If you add 4 to the number of pears, subtract 4 from the number of apples, multiply 4 by the number of oranges and divide 4 by the number of persimmons, you will get the same number. How many of the four fruits are there?

If the number of four kinds of fruits is equal to X after changing, then the number of fruits before changing is respectively: pear x-4, apple x + 4, orange x △ 4, persimmon 4x. According to the meaning of the question, we can get the equation: x-4 + X + 4 + X △ 4 + 4x = 100, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp

There are 125 kinds of fruits in total. If the pear is added with 4, the apple is subtracted with 4, the orange is multiplied by 4, and the number of persimmons is divided by 4, the number of them is equal. How many are there?
Fifth grade Jiangsu Education Edition comprehensive exercises on the topic of volume 12

Let X be the number. Pear is x-4, apple is x + 4, orange is x / 4, persimmon is 4x
The equation is: (x-4) + (x + 4) + X / 4 + 4x = 125
The solution of the equation is: x = 20
Pear x-4 = 20-4 = 16
Apple x + 4 = 20 + 4 = 24
Orange X / 4 = 20 / 4 = 5
Persimmon 4x = 4 * 20 = 80
A: there were 16, 24, 5 and 80

There are 100 pears, apples, oranges and persimmons. If you add 4 to the number of pears, subtract 4 from the number of apples, multiply 4 by the number of oranges and divide 4 by the number of persimmons, you will get the same number. How many of the four fruits are there?

The price of 7 kg peach is equal to the sum of 1 kg apple and 2 kg pear
The price of one kilogram of peach is equal to the sum of one kilogram of apple and two kilogram of pear. The price of seven kilogram of apple is equal to the sum of ten kilogram of pear and one kilogram of peach?

Suppose the price of apple is x yuan per kilogram, pear is y yuan per kilogram and peach is y yuan per kilogram
The kilogram is Z yuan
Then, according to the meaning of the title, the equations x + 2Y = 7z, 7x = 10Y + Z are set up
So buy 12 kilograms of Apple money can buy 18 kilograms of pear

Three apples and one pear are equal to the weight of ten peaches. One pear is equal to the weight of one apple and six peaches. One pear is equal to the weight of several peaches

The second condition to the first condition is equivalent to 4 apples + 6 peaches = 10 peaches, so 1 apple = 1 peach. If the first condition is brought in, a pear = 7 peaches. The answer is 7

There are 100 pears, apples, oranges and persimmons. If you add 4 to the number of pears, subtract 4 from the number of apples, multiply 4 by the number of oranges and divide 4 by the number of persimmons, you will get the same number. How many of the four fruits are there?
