$\begin{array}{l}\text{Here,}\\ \Rightarrow \text{? \% of 555 +28\%of 444 = 202.02}\\ \\ \text{It can also be written as}\\ \\ \Rightarrow \frac{x}{100}\times 555+\frac{28}{100}\times 444=202.02\\ \\ \Rightarrow 5.55x+28\times 4.44=202.02\\ \\ \Rightarrow \text{5.55}x\text{ = 202.02 -124.32}\\ \\ \Rightarrow \text{5.55}x\text{ = 77.7}\\ \\ \Rightarrow x=\frac{\text{77.7}}{5.55}\text{ =14}\end{array}$

Hence, Option C is correct.
