Since they bought the same total number of flowers, and roses are more expensive than daisies per flower, the person who purchased more roses spent more money than the other person.
So, the question becomes this: Did Kim purchase more roses than Sue did? If yes, then Kim spent more money than Sue did. If not, then Kim spent less money than Sue did.
Statement One Alone:
Kim bought twice as many daisies as roses.
Even though we know that Kim bought twice as many daisies as roses, we don’t know anything about the number of roses and the number of daisies Sue bought. Thus, we can’t tell who bought
more roses. Statement one alone is not sufficient.
Statement Two Alone:
Kim bought 4 more roses than Sue bought.
Since Kim bought more roses than Sue did, she also spent more money on the flowers than Sue did. Statement two alone is sufficient.
Answer: B
