% of e-mail users at work spend less than 15 minutes on e-mail per day.
time spent on e-mail at work
more than 3 hours: 7%
2–3 hours: 8%
1–2 hours: 6%
15–60 minutes: 50%

Explanation:

Step1: Sum known percentages

Sum the percentages of other categories: \(50\% + 6\% + 8\% + 7\% = 71\%\)

Step2: Find remaining percentage

Subtract from 100%: \(100\% - 71\% = 29\%\)

Answer:

29
