As always, a gr8 question!
The answer to the questions are 100 and 24.
For the first part,
Since there are 4 divisions between the 'Users in million' scale, the value of each division can be calculated as 125. The value of users at 2002 comes to be approximately, 625 and for 2007 it can be seen as 1375. The percentage change would be approx 750/625 % further reduced to 26/25% which can be approximately found as 100%.
Similarly, for the second part, the users in the year 2000 ~ 500 Total population ~ 6200 % value approx 7%
and users in 2010 ~ 2000 and total pop ~ 6800. % value approx 33%
The difference in % = difference in terms of 100 people ~ 24%
Hope its correct!
