Combinations That Sum To A Given Total?
Feb 26, 2014
I have up to 30 cells each with an integral value from 1 to 5. The task is to list all the ways that selections of from 1 to 5 cells can be made from the list such that the value of the sum of the selection is 5. It will usually be the case that there will be a final selection that will not sum to 5 and this needs listing also.
I am aware of coding that can list out combinations, but not in a form that can be adapted to deal with the summing limitation. I hope that I will be able to code so that I can deal with different numbers of cells and different sum values.

The aim is to find those combinations of variable values which generate highest total gain. I attached the spreadsheet which shows the variables (A through K) and a Gain column. I created 5 additional tabs which show all possible 2,3,4 and 5-member combinations of the variables. These tabs are like coordinates of which variable combinations should be examined. As an example I used the first combination from the second tab = A and B. If you look at these two columns on the EXAMPLE CALCULATION tab you will see 7,7 in the Number combination which is the first number pair for these two variables. The headings of the red and the yellow columns calculate the total count for this number pair and the total gain. These were recorded on a separate EXAMPLE RESULTS tab along with some other pairs which appear afterwards (these were recorded only from the first 39 rows of the AB data). I need a macro which will cycle through each variable pair (only using the combinations from the tab 2 for now, annd later from 3,4 and 5 tabs) collecting statistics for each unique number combination it encounters (printing to a separate sheet one after one), such as shown on the EXAMPLE RESULTS.

What I am looking for is to select between 7 and 15 numbers in total, I want all the possible 6 digit combinations for this.
EG: if I choose 2,9,11,13,15,17&26, it would look something like this
2,9,11,13,15,17
2,9,11,13,15,26
9,11,13,15,17,26
And so on.
If I chose more numbers (10) 1,2,3,4,3,6,7,8,9,10 it would start something like this
1,2,3,4,5,6
1,2,3,4,5,7
1,2,3,4,5,8
1,2,3,4,5,9
1,2,3,4,5,10
And so on.
Please remenber I would like to be able to secelt between 7 and 15 number and be given all the possible combinations.
I would like it to be in one sheet but if that can not be done on as many as it takes.
It would be good if I could just type the required number into A1,B1,C1 and so on and they just gave the combinations required.

I have a report which has a list of customers, each customer has 24 columns which represent the payment history over 24 months. If a payment has been made for that month the date and time (formatted correctly) will be populated in this cell.
Each customer has a product name attached to it so a product can appear several times. I need is a formula that shows the total payments recieved for a particular month for a particular product. For example.
I have managed to create the following flag which works a treat, it picks up a date an account was set up but looks at 1 column.

This may not be the best way to do this, but I don't know Macros or Pivot Tables.
I am looking for a way with formulas to do the following:
Within a workbook the 1st sheet is the data entry.
In another sheet that will total data from the data sheet is where I want to be able to total columns of data, depending on what is entered in one specific column:
Example:
Data Sheet, E2:E2999 is a unit number selcted by pull down tab entry.
G2:G2999 in the same sheet is where the data is.
Q: What formula would allow to total the data on the Total Sheet depending on what unit number is selected in column E on the Data Sheet and the data amount in column D from Data Sheet?

I'm sure this can be done but I don't think I have the formula correct. What I am trying to do is add each day's total while displaying a positive number if the total exceeds 6000.

number for item detail level from category standpoint. For example, in the category sheet has total number per category and per month and in the item detail sheet has a list of item number with category. I want a formula to recognize which item belongs to which category then use the total number of category by month to multiply with % of total in column D from Item Detail Spreadsheet.

I am trying to create a very basic workbook that has 2 worksheets. one is a daily input for tonnes, that then just gets cut and pasted to a different program, and the other worksheet is the running total. i.e., it adds up every time you update it.
been trying to figure out a macro so when you press the update button it then just updates the monthly total.

In an excel work shift schedule, I am trying to total the total number of days someone is scheduled for different shifts. I can get a total for the current schedule but I want to be able to have a year to date total as each new schedule is added in. These totals are in the AF through BC columns in the xray shift totals in the attached worksheet.
I don't know if it is possible or not and am working on a pre-existing worksheet.

I have a column of transactions lets say 500 or so, of irregular numbers such as 257,273.80 (not something ou can add up in your head...). I know that of those 500 transactions a handful of them have a sum of lets say 2,877,000.00, which I know. Now I need to find all possible combinations of values in this column that equal a sum I enter.

I have a sheet in my workbook with at least 180 small tables, there may be more.
I woulds like to be able to change total formulas for all tables at once to show either year-to- date or total year.
For example:
If we have only progressed through the second period of the year, I would like to choose something to indicate period 2. At other time I may want to know the total year whether the periods are completed or not.

I have 5 numbers (can be with decimals) in column A (A1:A5). For these
numbers, I want all combinations as well as the median of these
combinations.
I'm pretty far already. However, the median seems to be calculated
wrong.

I need to find possible combinations for the following example:
a*x + b*y + c*z = t
p = 10
Where
a = 0
b = 5
c = 10
t = 30
x + y + z has to = p
a, b, c, t, and p would be variables that I would specify. The numbers above are just examples. What I would need to see as output would be:
7a, 0b, 3c
4a, 6b, 0c
5a, 4b, 1c
etc...

I have a simple list of names with associated numerical values.
I would like to create a formula that will produce a series of all possible series of 8 of those names whose combined numerical values are at or below a certain threshold (or between two thresholds, if that's easy). Bonus points if the total combined value for each group is easily shown, but that'd just be gravy.

I want to have a sheet with all the previous drawings for the florida lottery.
Then I want excel to ask me how many numbers do I wish to play.
Then when I say 12 (for example) it would pick 12 numbers from 1 to 53 and match all possible comibinations of thoses numbers to the the previous drawings and tell me wich 12 number combination would have won more times then others. So it would need to compare each possible 12 nmber combination to each other and see wich one won more 6outof6, 5outof5, 4outof4, and 3outof3. Then give me the one with the highest winings

Here is what my table kind of looks like
A B
4 0.25
7 0.3
2 0.1
3 0.15
4 0.30
1 0.4
8 0.05
2 0.1
Now there is the number and the number(A) that it value it represents (B). This is what I want. I want to see all possible number combinations between the upper and lower A columns listed veritcally under the whole set, with out duplicating any numbers and with the upper numbers only being in the 1st position and the lower numbers being in the second position Ex( 4-1, 4-8, 4-2, 7-4, 7-1, ect, ect (listed vertically). Now in column B under, right beside each possible combination I want to see the result of the two values multiplied (ex. beside 4-1 I would like to see 0.1)
So below that mess listed above I want to see something like this
A B
4-1 0.1
4-8 0.0125
ect
ect
ect
I want to be able to swith the values around and have it automatically make the correction.

I am trying to create a combination list. I have 48 items and I want to create all possible comibinations of 3 items from this group of 48 items.
I did something similar to create all possible combinations of 2 items from the group of 48 items in the attached spreadsheet. This was done manually and was time consumning. I want to do something similar for all possible combinations of 3 items from this group of 48 items.
All my 48 items are listed in rows 4 and 5. I want to enter the number "1" in each column to indicate my selection. Right now I have 2 ones per row. But I want to do 3 ones per row.

I need to find the possible combinations for several arrays consisting of binary data. I shall give a simplified example with three arrays and four fields. Lets assume the three starting arrays look as follows:
1 0 0 0
1 0 0 0
1 0 0 0
Each row may contain one field = "1" and all other fields = "0". So the next possible combinations may be:
1 0 0 0
1 0 0 0
0 1 0 0
1 0 0 0
1 0 0 0
0 0 1 0
etc...until:
0 0 0 1
0 0 0 1
0 0 0 1
Assuming k = number of fields and c = number of arrays the possible combinations are k ^ c = 4 ^ 3 = 64. I am looking for vba coding that allows to cycle through all possible combinations and displays them in an excel spreadsheet. Ideally, the code should work for any k and c. Could anyone please give me any pointers as to how to tackle this problem?
p.s. in essence I'm looking for the tabular representation of a tree plan with four branches to commence with, a total of 16 decision nodes, and two possible outcomes (1 and 0)

Can this be done in Excel? Using the digits 0,1,2,3,4,5,6,7,8,9 create all the permutations/combinations with limits on some of the digits. The digits 0,7,8,9 can only be used a max of 3 times in any one permutation/combination, digits 2,3,4,5,6 can only be used 4 time in any one permutaion/combination, producing a 5-digit string.
Example of expected results.

Outside the door of my flat I have a key holder – which has a combination of 4 digits. No-one knows what the combination is, so I’d like to try to find it, clear it and use it.
I wondered if there was a way to use excel to show all of the possible combinations so I can then tick them off as I try them…?
The possible numbers are 0-9, but you cant press a button more than once in any given attempt… so… first possible combination would be 0123… not 0001.
