Generating random numbers and percentages of numbers

Question

The issue that I'm having is how to randomly generate the a random number and then randomly distribute the product over 10 variables. The product of all 10 percentage variables should equal 100% of the total given in the first random function.

Here's an example of what I mean:

x= randomly generated number from 10000-25000

a=(random)% of x
b=(random)% of x
c=(random)% of x
d=(random)% of x
e=(random)% of x
f=(random)% of x
g=(random)% of x
h=(random)% of x
i=(random)% of x
j=(random)% of x

x=sum(a,b,c,d,e,f,g,h,i,j)=100% of x

The result only requires a number greater than 0 and repeated percentages are not a problem as long as they are randomly generated.
Thanks for any input, I'm still learning C# after a long recess from C++

I am sorry but I do not have the time to do all the programming for you. If there is something specific you need help with then I will try to help and there are many others here that are eager to help with specific questions. If you were to write a sample using C++ then it could easily be converted to C#.

Thanks Sam Interesting possible solution Could you give me an example of what you're saying in code? thanks again

Maybe this will help. Sum all percentages that have been obtained; in the beginning that would be zero of course. Subtract the sum from 100 and use the result as the range for the next random number generation. Of course yoiu don't need to do the sum each time; you can simply subtract the previous percentage from the previous range to get the next range. So in other words randomly generate percentages.
