• Question 1:

  If W is divisible by 7, is Z even or odd?

  (1)

  Z = W+1.

  (2)

  W = 7.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: E

  From the question we don't know if W is even or odd (W = 7, 14, 21, 28...) so statement one also is not helpful. From statement two we get no connection to Z so it's not sufficient either.

• Question 2:

  If X is divisible by 4, is Y odd?

  (1)

  Y = x + 3.

  (2)

  X = 4.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: A

  From the question one can conclude that x is even. From statement one: an even number + odd number is an odd number. Thus, y must be odd. Statement two doesn't mention y at all, and is therefore insufficient

• Question 3:

  Bob is older than his brother, Jimmy. How old is Jimmy?

  (1)

  Two years ago Jimmy was one-third of bob's age today.

  (2)

  In six years from today Bob will be three times Jimmy's age today.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: E

  Build an equation from each statement both equations are identical. Since we need two different equations to find two unknowns, we cannot solve this question.

• Question 4:

  Ruth's age is two-thirds of Chris's age. How old is Chris?

  (1)

  Two years ago Ruth was half the age Chris is today.

  (2)

  Four and a half years from now Ruth will be seven eights of Chris's age.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: D

  From the question we know that R (Ruth) = (Chris). That's one equation with two variables; we need one more equation to solve the problem. Both statements are suitable equations and thus the answer is (d).

• Question 5:

  X is a prime number. Is Y odd?

  (1)

  X is divisible by 7.

  (2)

  YX is an even number.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though

  NEITHER statement BY ITSELF is sufficient.

  D. Either statement BY ITSELF is sufficient to answer the question.

  E. Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: C

  From statement one we conclude that X=7 because it's the only prime number that can be divided by 7. From statement two we conclude that if X was a odd number Y must be an even number, therefore both statements are required in order to solve the question.

• Question 6:

  Jasmine is the oldest member of the "Brain Storm club". If next year, the age of Sam will be two thirds that of Jasmine, what is Sam's age today?

  -Rick is Sam's twin brother.

  -

  Three years ago, Rick's age was half of that of Jasmine.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: C

  Define J as the age of Jasmine and S as the age of Sam. The question tells us that in a year from now: (S

  + 1) = 2/3 x (Y + 1). Statement (1) presents a new parameter, Rick's age, which is equal to Sam's age.

  Statement (2) tells us that: (X -3) = -x (Y -3).

  Using both statements, we have two equations with two unknowns.

• Question 7:

  How long does it take to drive from the factory to the warehouse?

  -

  It takes 15 minutes to drive from the factory to the harbor.

  -

  It takes 25 minutes to drive from the warehouse to the harbor.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: E

  From both statements we can't conclude where the location of the harbor relative to the other two places

  is, in other words, the harbor could be between the factory and the warehouse or it could be beyond the

  two.

  The distance between the factory and the warehouse can be between 10 and 40 miles.

• Question 8:

  What is the distance between Greentown to Blue town?

  -

  The distance between Greentown and Red town is 20 miles.

  -

  The distance between Blue town and Red town is 5 miles.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: E

  Draw a guiding chart with three points on it.

  Statement (1) tells us nothing about Blue town and so it's insufficient. Statement (2) tells us nothing about

  Greentown and so it's insufficient on its own. Even after you combine both statements, you don't know if Red town is between both cities or not. The distance from Greentown to Blue town can be 25 or 15 miles. More data is required.

• Question 9:

  Comp and Calc are two companies that are located on different floors in a skyscraper. How many floors does the skyscraper have?

  -

  There are 24 floors between Comp's floor and Calc's floor.

  -

  There are 32 floors above Comp's floor and 12 floors bellow Calc's floor.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: C

  Using both statements we know that Comp's floor is the higher one among the two because there are only

  12 floors beneath Calc's floor and therefore it must be the lower one. The number of floors in the building is

  (12 + 24 + 32 = 68).

  The combination of the two statements is sufficient.

• Question 10:

  Arthur and Bartholomew live in the same multi-story apartment building. How many stories does the building have?

  -

  There are 5 stories between the apartment of Arthur and Bartholomew.

  -

  There are 8 stories above Arthur's apartment and 8 stories below Bartholomew's apartment.

  A.

  Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

  B.

  Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

  C.

  Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

  D.

  Either statement BY ITSELF is sufficient to answer the question.

  E.

  Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.

  Correct Answer: E

  Define A as the Arthur's floor and B as Bartholomew's floor. Using both statements, we don't know whether A is over B or the opposite and therefore we cannot determine the number of stories in the building. If A is above B then: The number of stories is (5+8+8 = 21). If B is above A then: The number of stories is (5+3+3 = 11).
