Preathi’s approach
Unique google docs, edited by active users globally on a weekday. Total world population = 8 Billion Global internet users = 60% of 8 Billion = 4.8 B (because only internet users can access google docs) Removing china from 4.8 Billion people, as they don't have google, so 30% of 4.8 B = 3.4 B No. of active users using google docs = 60% of 3.4B = 2 Billlion No of users who open and edit a document in a typical weekday = 30% of 2 B = 0.6 B Average unique documents users edit in a typical weekday = 2 So, 0.6 B * 2 = 1.2 Billion unique docs people actively edit globally on a weekday
