GMAT Club Official Solution:A neighborhood bakery owner selected some pastries to feature in a weekend display case. Was the number of selected pastries that were fruit-filled but not topped with glaze less than the number of selected pastries that were topped with glaze but not fruit-filled? (1) Every selected pastry that was fruit-filled was also topped with glaze.
If every fruit-filled pastry was also topped with glaze, then the number of pastries that were fruit-filled but not topped with glaze is 0.
The question thus becomes: is 0 less than the number of pastries that were topped with glaze but not fruit-filled?
That could be YES if that number (the number of pastries that were topped with glaze but not fruit-filled) is positive, or NO if that number is also 0.
Not sufficient.
(2) Every selected pastry that was not fruit-filled was also not topped with glaze.
If every pastry that was not fruit-filled was also not topped with glaze, then the number of pastries that were topped with glaze but not fruit-filled is 0.
The question thus becomes: is the number of pastries that were fruit-filled but not topped with glaze less than 0?
Since that number cannot be negative, the answer to the question is NO.
Sufficient.
Answer: B.
