Data-Sufficiency
Exactly how many paper clips does John have in his packet?
(1) John has fewer than 5 paper clips in his packet.
(2) John has more than 3 paper clips in his packet.
From Statement (1) alone, we can only say that the number of paper clips in John’s packet is 1, 2, 3 or 4. And this will not give us the unique answer.
So, (A) is not the answer.
If Statement (2) alone is given, we can say that the number of clips in John packet may be 4, 5, 6, 7, 8 etc…
So, Statement (2) alone does not help us to answer the question uniquely.
So, (B) is not the answer. If both the Statements (1) and (20 are given, we can say that John has exactly 4 clips in his packet because this is the only number which satisfies the conditions given in the two statements.
So, (C) is the answer.
