Official Explanation

The graph indicates that there were approximately 700 million Internet users in 2002 and approximately 1,400 million in 2007. Thus, between 2002 and 2007, the percent increase in the number of Internet users was approximately (1,400−700)/(700) (100)% = 100%.

The correct answer is 100.

The graph indicates that in 2000 the population was approximately 6,100 million, of whom approximately 400 million were Internet users, and in 2010 the population was approximately 6,875 million, of whom approximately 2,100 million were Internet users. Thus, in 2000 there were 100(400/6,100) ≈ 6.6 Internet users per 100 people, and in 2010 there were 100(2,100/6,875) ≈ 30.5 Internet users per 100 people. Therefore, from 2000 to 2010, the number of Internet users per 100 people increased by approximately 30.5 − 6.6 = 23.9 ≈ 24.

The correct answer is 24.
