reading the statement could be a little blurry.
Basically the question is asking which is the % of time dedicated to the internet by people in their 50's on the total amount of time of hours/week spent by the same cluster as a whole.
I.E.
the purple section represents in the second graph the total amount of hours by the 50's spread among all the resources, which is 41 hours
On the internet they spent 2 hours per week
\(\frac{x}{100}\) of 41 is 2
\(\frac{x}{100} 41 = 2\)
\(x=\frac{200}{41} \approx\) 5%
B is the answer
