Question : 85 of 100

Marks: +1, -0

A store bought Q windows at

150 per window and W shelves at

75 per shelve. What is the total price of the windows and the shelves?
(1) The

Q

windows cost

\$ 600

.
(2)

Q+W \/ 2=12

Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.
Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.
Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.
Either statement BY ITSELF is sufficient to answer the question.
Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

Solution:

Statement (1) is all about the windows and therefore it is not sufficient by itself.
Statement (2) tells us that

Q+W \/ 2=12

, this is sufficient because the total price of windows and shelves is

150 Q+75 W

.
Multiply the data in statement (2) is 150 to get:

150 Q+75 W=18,000

. Statement (2) is sufficient by itself.
