So, Steve's time in a ratio to Paul's time:
[tex] \frac{Steven's time}{Pauls's time} = \frac{10}{12} = \frac{5}{6} . [/tex] So Steven's time is [tex] \frac{5}{6} [/tex] times shorter, that is
"Steven is [tex] \frac{5}{6} [/tex] times faster than Paul (I find the phrasing "as fast as" problematic though)
In the second question 41% of 400, which is 4*41=164 people chose WWCN and 22% chose WANR, that is 22%*400=4*22=88.
And the difference is 76 people! ( 164-88=76)B)

Answer:
Q-1 The correct option is A) Steve is 5∕6 as fast as Paul
Q-2 The correct option is 76.
Step-by-step explanation:
Consider the provided information.
Q-1
Steve can complete the 100m dash in 10 seconds while Paul can run it in 12 seconds.
Since, the distance for both are same,
[tex]\frac{\text{Steve's time}}{\text{Paul's time}}=\frac{10}{12}=\frac{5}{6}\\\text{Steve's time}=\frac{5}{6}\text{ of Paul's time}}[/tex]
Hence, Steve's time is 5⁄6 of the time taken by Paul.
Therefore, the correct option is A) Steve is 5∕6 as fast as Paul
Q-2 a survey in which 400 people were asked to identify the TV channel on which they preferred to watch the evening news.
WWCN got 41% and WANR got 22%
For WWCN
41% of 400 is: [tex]\frac{41}{100} \times 400=164[/tex]
That means 164 people preferred WWCN.
For WANR
22% of 400 is: [tex]\frac{22}{100} \times 400=88[/tex]
That means 88 people preferred WANR.
We need to find how many more people preferred WWCN
For this subtract both the values: 164-88=76
Thus, 76 more people preferred WWCN
Hence, the correct option is 76.
