2. The ratio of the weight of one small box to the weight of one big box is \frac{3}{7} .


How can you immediatly tell that the second statement only reiterates the information provided by the stem ?

Given: 4s+5b=11s+2b --> 3b=7s.
Question: s=?

(1) b=s+1 --> 3b=3(s+1)=7s --> s=\frac{3}{4}. Sufficient.
(2) \frac{s}{b}=\frac{3}{7} --> 3b=7s, the same info as in stem. Not sufficient.

Answer: A.
