If Rahul earns a raise of between 5% and 10%, non-inclusive, by what fraction could her salary have increased?  Choose the correct option:
A) 1/4 B) 1/5 C) 1/10 D) 9/100 E) 1/20
Perhaps it is also easy to just translate the % into fractions:   6%: 6/100 = 3/50   7%: 7/100   8%: 8/100 = 4/50 =2/25   9%: 9/100   Only 9/100 exists in the answer choices, so ANS 9/100
