Can anyone help me to solve this? I do not know how to use the contraint on C3 and how to implement ri in it!

I think that this is a straightforward problem is you use the problem-based optimization workflow, which requires a relatively recent version of Optimization Toolbox™.

So you were able to program it. Good for you!

Now let's look at your constraints:

cons1 = sum(x) <= 10;
cons2 = sum(r.*x) >= 10;

The r variable has all entries between 0 and 1, and the x variable is nonnegative. Therefore, for any x satisfying cons1, the value of sum(r.*x) is smaller. Therefore your constraints are inconsistent.
