32% of the same people spend their time listening.
The total number of mentioned people will be 100% or 1. Now, in the total people, the remaining ones who are not stated in the question, must be the listeners. Thus, calculating the remaining percentage of people, we will get the percentage of listeners in same people.
So, number of people who spend time speaking = 26%
Number of people who spend time speaking = [tex]\frac{26}{100}[/tex]
Number of people who spend time speaking = 0.26
Number of people who spend time writing = 23%
Number of people who spend time writing = [tex]\frac{23}{100}[/tex]
Number of people who spend time writing = 0.23
Number of people who spend time reading = 19%
Number of people who spend time reading = [tex]\frac{19}{100}[/tex]
Number of people who spend time reading = 0.19
Total number of people involved in activities other than listening = 0.26 + 0.23 + 0.19
Total number of people involved in activities other than listening = 0.68
People who spend time listening = 1 - 0.68
People who spend time listening = 0.32
Percentage of people who spend time listening = 0.32 × 100
Percentage of people who spend time listening = 32%
Hence, 32% of the same people spend their time listening.
