9. Party A and Party B go shopping together on Sunday, and the money they bring with them is 86 yuan. In Friendship Shopping Mall, Party A spent 4/9 of his own money on a pair of sports shoes, and Party B spent 16 yuan on a shirt. In this way, the money left on them is exactly the same. How much money did A and B originally bring?

Find out the difficulty of five different types of mathematical problems;
The sum of 200 1 consecutive natural numbers is equal to the product of four different prime numbers. Find the minimum value of the sum of these four prime numbers.
answer
Let the first number of 200 1 natural number be a, then the sum of 200 1 natural number is equal to (a+ 1000)×200 1, which is equal to the product of four different prime numbers, 2001= 3× 200.
Difficulty:
Please write five prime numbers, they are arithmetic progression, and the tolerance is 12.
answer
Remember, all the prime numbers within 100 are odd except 2, and the number at the end of the odd arithmetic progression with a tolerance of 12 must be 1, 3, 5, 7, 9, so there are only 5 prime numbers ending in 5, and the five prime numbers are 5, 17, 29, 49 respectively.
Difficulty:
( 10+876+3 12)×(876+3 12+9 18)-( 10+876+3 12+9 18)×(876+3 12)=
answer
Detailed explanation: This question uses method of substitution.
Suppose: 876+3 12=A, 876+312+918 = b.
The original formula = (10+a) × b-(10+b )× a.
= 10B+AB- 10A+AB
= 10(B-A)
Because, B-A = (876+312+918)-(876+312) = 918.
So the original formula =9 180.
Difficulty:
A new three-digit number can be obtained by arbitrarily exchanging a three-digit number sequence. Can the sum of the original three digits and the new three digits be equal to 999?
answer
Cannot be equal to 999. Because a new number is obtained by changing the order of each bit of a three-digit number, the sum of each bit of this three-digit number is equal to the sum of each bit of the new number obtained after changing the order. The sum of these six figures is even, while the sum of 999 is 27, which is odd, so it cannot be equal to 999.
A natural number greater than 10 is divided by 90 and 164, and the sum of the two remainders is equal to the remainder obtained by dividing the natural number by 220. What is this natural number?
answer
The sum of two remainders obtained by dividing this natural number by 90 and 164 is equal to dividing this natural number by 90+ 164=254, so the remainders obtained by dividing 254 and 220 by this natural number are the same, so this natural number is a divisor of 254-220=34, and this natural number can only be 17 or 34. Then the remainders obtained by dividing by 90, 164 and 220 are 22, 28 and 16 respectively, which does not meet the requirements of the topic. If this number is 17, then the remainders obtained by dividing by 90, 16 and 220 are 5, 165438 respectively.
I am also a graduate of the sixth grade mathematics graduation paper.
Not yet.
You can check the previous papers.
I wish you good grades in the exam.
If a is a multiple of 50, write a question for the sixth grade math graduation exam.
It can be (a/50) bagged.
If a is not a multiple of 50
It can be packed in [a/50]+ 1 bag.
Where [a/50] represents the largest integer less than a/50.
For example, a=60, [a/50]=[ 1.2]= 1.
