We know that the number of users triple each day
Let number of users on day 1 be x
⇒ Users on day 2 =
= 3x
and Users on day 3 =
= 9x
And so on...
% Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 
⇒ % Increase in users from day 1 to day 2 = 200%
Similarly,
% Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 
⇒ % Increase in users from day 2 to day 3 = 200%
Hence, we can see that the percentage increase each day is 200%
Didn't I answer this one? It's x = to 62. YOU'RE WELCOME :D
1000x2x15=30000
30000-1000x15=15000
1000x15x5=75000
75000-1000x5=70000
100x15x15=22500
22500-15x100=21000
