Jiang Yihan originally wanted to answer the second question slower because he was answering the first question too quickly. Jiang Yihan raised his eyes and looked at the lit incense burner, there was still half a length, and there was still time, so he frowned as if he was contemplative and dissociated, but he didn't expect that it was not a big deal to watch the play, and there were many discussions on the side, and the laughter was harsh.

"You can't see it! I'll just say he had a problem with the first question. ”

A man with a sharp mouth and monkey cheeks stared at Jiang Yihan with a sneer, as if he had some deep hatred, and that resentment had to make people look at it twice.

"Phew! What's the matter, your eyes can still "Yue Gongzi is too merciful, and he doesn't want to let a few distinguished guests"

A total of 1,000 pears and fruits were bought for 999 yuan, 9 pears were bought for 11 yuan, and 7 fruits were bought for 4 yuan. Q: How many pears and fruits do you buy, and how much do you pay for each?

Price per pear: 11÷9=12/9 (text)

Price per fruit: 4÷7=4/7 (text)

Number of fruits:

(12/9×1000-999)÷(12/9-4/7)=343 (pcs) number of pears: 1000-343 = 657 (pcs) total price of pears:

12/9×657=803 (text)

Total price of fruit:

4/7×343=196 (text)

Solution: Let the pear be X and the fruit be Y

x+y=1000

11/9X+4/7Y=999

Solution: X=657;Y=343

That is, the number of pears is 657, and the money is: 657*11/9=803

The fruit is 343, and the money is: 343*4/7=196

Today, there are things that do not know their number, the remaining two of the three or three numbers, the remaining three of the five or five numbers, and the remaining two of the seven or seven numbers, asking the geometry of the object. In today's words: "There is a batch of items, three three lots are more than two, five five lots are more than three, seven seven places are more than two, and ask how many items there are in this batch." The solution to this problem is called

Three people walk together seventy (seventy) rare,

Twenty-one (21) branches of five plum blossoms,

Seven sons are reunited in the first month and a half (15),

Except for one hundred and five (105).

Each sentence in the song is a one-step solution: the first sentence means that the remainder of the division by 3 is multiplied by 70; The second sentence refers to dividing the remainder by 5 and multiplying it by 21; The third sentence refers to dividing the remainder by 7 and multiplying it by 15; The fourth sentence refers to the sum of the three products multiplied above, if it exceeds 105, subtract the multiple of 105 to get the answer. Namely:

70×2＋21×3＋15×2－105×2=2
