Question

Assume you have a room of 10 Facebook users and the average number of friends is 130. If one person in this room adds 50 new Facebook friends (none of whom are in the room), then what would be the new average number of Facebook friends for these 10 people?

Answer 1

average number of friends is 130

So total number of friends of 10 facebook user = 10*130=1300

 

If one person in this room adds 50 new Facebook friends so toatal number of friends of 10 facebook user=1300+50=1350

 

new average = 1350/10=135
