Explanation:

Step1: Calculate total number of people surveyed

Add the number of people in each category: \(160 + 740+1100\).

$$160 + 740+1100=(160 + 740)+1100 = 900+1100=2000$$

Step2: Calculate the percentage of completely - satisfied people

Use the formula \(\text{Percentage}=\frac{\text{Number of completely - satisfied people}}{\text{Total number of people}}\times100\%\).
Substitute the values: \(\frac{1100}{2000}\times100\%\).
