Evaluate Each Statement Separately

Step 2: Evaluate Each Statement Separately, continued
Now we’ll return to Statement (1):
A batch of cookies is divided among three
jars. What fraction of the cookies is placed in the third jar?
(1) 1/3 of the cookies
are placed in the first jar, while 13 of the cookies are placed
in the second jar.
(2) The jars contain a
total of 36 cookies, and 30 of those are in the first two
jars.

Insufficient. |

Statement (1) does not provide
enough information. It states that a third of the cookies are in the first
jar and that 13 cookies are in the second jar. But a third of how many?
We can't get the total, so Statement (1) is insufficient.
We already knew that Choices
(A), (C), and (E) weren’t correct based on our answer to Statement (2).
Now we know that Choice (D) is also incorrect, which leaves us with the
correct answer, Choice (B).
|
Statement (1) BY ITSELF is
sufficient, but statement (2) by itself is not sufficient. |
|
Statement (2) BY ITSELF is
sufficient, but statement 1 by itself is not sufficient. |
|
Both statements TAKEN TOGETHER
are sufficient, but NEITHER statement BY ITSELF is sufficient. |
|
EACH statement BY ITSELF is
sufficient. |
|
The two statements TAKEN TOGETHER
are NOT sufficient. |
When applying Step 2, don’t
let the information in one statement influence your decision about the
other statement! Consider them separately.
What would you have done if each
of these statements had been insufficient? In that case, you would have
gone to Step 3 of the CAT Method.
