Anonymous users2024-02-08A total of 15 different currencies can be formed.
Analysis: In the question, one RMB of each of the four different currency values, that is, any one, two, three, and four of the four different currency values of RMB are taken as a group and combined.
1. 1 RMB alone: 1 yuan, 2 yuan, 5 yuan, 10 yuan, a total of 4 currency values.
Zhang RMB Portfolio:
1+2=3 (yuan), 1+5=6 (yuan), 1+10=11 (yuan), 2+5=7 (yuan), 2+10=12 (yuan), 5+10=15 (yuan).
There are 6 different combinations to get 6 different currency values.
Zhang RMB Portfolio:
1+2+5=8 (yuan), 1+2+10=13 (yuan), 1+5+10=16 (yuan), 2+5+10=17 (yuan).
There are 4 different combinations to get 4 different currency values.
RMB combination: 1 + 2 + 5 + 10 = 18 (yuan).
A total of 1 different combinations to get 1 different currency value.
Add the value of the above four combinations to 4+6+4+1=15 (kinds), so there are 15 combinations in total.
This is a combinatorial problem in mathematics. Taking any of the m (m n) elements as a group from n (4 in the problem) is called a combination of m elements from n different elements. This problem of finding the number of combinations is called a combination problem.
The number of combinations can be calculated directly with the formula as:
As in the question: n=4, m are 1, 2, 3, 4 respectively.
The result of calculating m equals 1,2,3,4 is: 4,6,4,1. Add the results together to get 15. That is, there are 15 different combinations.

There are ten dollars, five dollars, two dollars, one dollar, five different ways to buy a book worth ten dollars, and this is how it is calculated
Yuan x1 = 10 yuan.
Yuan x2 = 10 yuan.
Yuan x1 + 1 yuan x 5 = 10 yuan.
Yuan x1 + 2 yuan x 2 + 1 yuan x 1 = 10 yuan.
Yuan x1 + 2 yuan x 1 + 1 yuan x 3 = 10 yuan.

The 1965 edition of the 10 yuan banknote is one of the more common varieties in the third set of renminbi and has a certain collection value. However, it is currently in large quantities and is readily available on the numismatic market, so it has little potential for appreciation. >>>More
Hello, According to the market, the ordinary version of the 1999 one-yuan banknote has no collectible value, and some special numbers and special prefixes of the 1 yuan banknote have a certain collectible value. In the collection market, we usually call the RMB crown tail 3 with the same number as the leopard, the tail 4 with the same as the lion, the tail 5 with the tiger number, the tail 6 with the same name as the elephant, the tail 7 with the same name as the dinosaur, the tail 8 with the same name as the unicorn, the 123456 such as the Shunzi number, the 00000001 such as the opening number, 10000000 such as the door after the closure, 20100923 such as the birthday number, like the above special number collection ** is very good, A 99-year-old one-dollar note of a Kirin banknote** can even be sold for tens of thousands of yuan.
It's basically not worth much anymore.
Although in 1960, the yuan was indeed very valuable, but now the yuan is no longer worth much, and it has little purchasing power. If you look at the collection value alone, the amount of one yuan held this year is also very large, so it is not valuable. I think if you have a lot of money like this, you can choose to continue collecting, you can choose to go to the bank to exchange it. >>>More
