Lesson: Data Sufficiency Basic - 11t01

Evaluate Each Statement Separately

[Page 11 of 22]

Step 2: Evaluate Each Statement Separately, continued

Now we’ll return to Statement (1):

Evaluate Statement (1) and select Sufficient or Insufficient, then click Continue.

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.

  Sufficient Insufficient.    

Countinue

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.
