By what percent did the population of Belleville increase from 2001 to 2003 ?

(1) The population of Belleville was 72,000 people in 2003.
(2) The population of Belleville doubled from 2001 to 2003.

To find the percentage increase we need

(New - old)/old

Here we only have the new which is not enough.

Statement 1 is insufficient.

Statement 2)

(New - old)/old

Tells us new = 2*old

2 old - old = old/old = 1*100 = 100%

B is sufficient
