Esther is giving Christmas presents to her family members. Each family member gets the same number of presents and no presents were leftover. If each family member gets at least one present, did each family member receive more than one present?
(1) Esther has forty Christmas presents to give out. -
Statement 1 is clearly insufficient, for we don't know the number of members. (2) If the number of family members were doubled, it would not be possible for each family member to get at least one present -
Ok, let's consider a case. Let the number of family members be 10 and the number of gifts be 15. The statement says that if the number of faimly member is doubled (So, the number of family member becomes 20), Everyone won't receive a give. Some would be left out. And the case that we took fits very well. 20 members won't be able to share the 15 gifts while ensuring that each member gets a gift. Hence when considering with 10 people and dividing 15 gifts among then, not all the members gets more than one. There will always be individuals limited to just one gift. - Hence, this one is sufficient.
Therefore B.
Correct me if I am wrong.
