Data sufficiency ?

by Pugalenthi » Fri May 11, 2012 11:42 am
Of the 11 movies playing at a certain cinema complex, some are action movies and some are more than two hours long. How many of the movies are action movies but are two hours long or shorter?
(1) All of the action movies playing at the complex are also two hours long or shorter.
(2) 4 of the movies playing at the complex are not action movies and are two hours long or shorter.
   
(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
(B) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
(C) BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
(D) EACH statement ALONE is sufficient.
(E) Statements (1) and (2) TOGETHER are NOT sufficient.

In stmt 2, are the remaining movies are action movies (11 -7=4)? If yes, by combining 1 and 2, we can answer the question. Is my assumption about stmt 2 valid?

Yes, we can arrive at the answer by using the two statements and the assumption that you talked about!

IMO: B

11 action movies can be classified as below:

1. Action movies, which are two hours shorter.
2. Action movies, which are two hours longer.
3. Non Action movies, which are two hours longer.
4. Non Action movies, which are two hours shorter.

We need to find 1) and 2)

Statement 1: No extra information given. INSUFFECIENT

Statement 2: 3)+4) is given i.e, 4
Hence 11-4 = 7 should be 1) and 2) SUFFECIENT
