The required cup of milk is 4 for serving 8 persons
What is unitary rule?
If we have two components of any variable ratio then first we find for 1 unit of change then we further calculate for required.
How to find solution of unitary rule?
Here we have given
5 persons served by 2 [tex]\frac{1}{2}[/tex] cup of milk
Therefore calculate for 1 person required
1 person need = [tex]\frac{2.1/2}{5}=\frac{5}{10}=\frac{1}{2}[/tex]
Now for 8 persons serving the required milk is
8 x 1/2 = 4 cup
Therefore the correct option is (c).
