If Renee earns a raise of between 5% and 10%, non-inclusive, by what fraction could her salary have increased?
Pick:
A) 1/4  B) 1/5  C) 1/10  D) 2/25  E) 1/20
5% is 5/100 = 1/20   10% is 10/100 = 1/10   The increase must be greater than 1/20 and less than 1/10.   1/4, 1/5, and 1/10 are not less than 1/10.   1/20 is not greater than 1/20.   The only option left is 2/25, which is in the specified range.   ANSWER:2/25
