Real-Life Math -- Solution

Option A

Percentage of techies = 80 / (80 + 125) x 100
Percentage of techies = 80 / 205 x 100
Percentage of techies = 39

Thirty-nine percent of the video newsgroup consists of techies.

You can't use option A because the share of techies is less than 75 percent.

Option B

Total hours that 1 gamer spends on techie questions = (6 minutes / 60 minutes per hour) x 10 questions
Total hours that 1 gamer spends on techie questions = 0.1 x 10
Total hours that 1 gamer spends on techie questions = 1

You can't use option B because gamers spend more than 45 minutes per week reading techie questions.

Option C

Total hours that 1 techie spends on questions = (6 minutes / 60 minutes per hour) x 25 questions
Total hours that 1 techie spends on questions = 0.1 x 25
Total hours that 1 techie spends on questions = 2.5

So that means techies spend 2.5 hours reading questions.

You suggest option C because techies spend more than 1 hour reading questions and they form more than 30 percent of the group.
