How many balls are contained in a certain box?
I. The balls can be evenly divided into groups, each group having a dozen balls.
II. There are more than 130 but fewer than 140 balls in the box.

Options

A. If statement (I) alone is sufficient to answer the question.
B. If statement (II) alone is sufficient to answer the question.
C. If either (I) or (II) alone is sufficient to answer the question.
D. If both statements (I) and (II) taken together are sufficient to answer the question.

Answer

D

Explanation

In this question statement I alone is not sufficient to answer the question because the total could be any multiple of 12
Statement II also just defines a range for the total But both statements taken together are sufficient to answer the question, for there is only one multiple of 12 between 130 and 140 i.e. 132.
Therefore, the answer choice is (d).
