  How many bananas did Jerry the monkey eat today?

  (1)

  Today, Jerry ate 30% more than his regular average.

  (2)

  Yesterday, Jerry ate 32 bananas, which is 15% less than his regular average.

  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 both statements together we know the average amount of bananas eaten by Jerry and that today Jerry ate 30% more than his regular average. Therefore, both statements together supply sufficient information to answer the question.

• Question 172:

  How many steaks did the restaurant sell between 20:00 P.M and 21:00 P.M on Wednesday?

  (1)

  On Tuesday the restaurant sold 25 steaks between the hours of 20:00 P.M and 21:00 P.M.

  (2)

  The average amount of steaks that are sold on Wednesdays is 25 steaks per hour.

  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

  Both statements do not provide us with any vital information about the specific number of steaks that were sold on that specific hour. The average is not accurate enough for the question and the sales of Tuesdays could be different than those in Wednesdays. Therefore, more sufficient data is required.

• Question 173:

  Tower X is smaller than tower Z. Is tower Y bigger than tower X?

  (1)

  Tower Z higher than tower Y.

  (2)

  Tower Y is one of the tallest in the world.

  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

  We can write the data that is given to us: X < Z.

  From statement (1) we can learn that: Y < Z also, this is not enough. From statement (2) we know that Y is

  very tall, one of the highest in the world, but X can still be higher. Therefore, more sufficient data is

  required to answer the question.

• Question 174:

  There are two major statues in Tasmanian County; the first is no more than 45 meters high. How tall is the second statue?

  (1)

  The second statue is 10 meters higher than the first statue.

  (2)

  Both statues together are 80 meters high.

  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

  The information on the first statue in the question is confusing and irrelevant. Statement (1) tells us that: B

  = A + 10 (A is the first and B is the second statue). Statement (2) tells us that: A + B = 80, therefore we

  have two equations with two variables and so we can solve the problem.

  Therefore, both statements are required in order to answer the question.

• Question 175:

  If building X is less than 40 store's high, is building Y taller than X?

  (1)

  Building Y is at least three times as high as building X.

  (2)

  On the fortieth floor of the Y building there is a gift shop.

  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

  Statement (1) tells us clearly that the Y building is taller than the X one. Statement (2) implies that there is a gift shop on the 40'Th floor; therefore there are at least 40 floors on the Y building, which make it taller than X. Both statements, by themselves, are sufficient enough to answer the question.

• Question 176:

  Ron has three kinds of shirts in his closet, white shirts, black shirts and fancy shirts.

  What is the ratio between the shirts in the closet?

  (1)

  The total number of shirts is 100.

  (2)

  30% of the shirts are black, which is twice as much as the fancy shirts.

  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 (1) we know the total amount of shirts in the closet.

  Statement (2) gives us the ratio between the shirts.

  30% of the shirts are black (which is 30 shirts), this number is twice as much as the fancy shirts (15).

  The remaining shirts must be white. We know the ratio; therefore both statements are required in order to

  answer the question correctly.

• Question 177:

  "Queens" is a game of cards that distinguishes the cards into three groups: reds, blacks and jokers. Four packets of cards are shuffled and only 50 cards are drawn out. How many red cards are in the stack of the 50 cards?

  (1)

  The number of black cards is twice the number of red cards.

  (2)

  There is at least one joker in the stack of cards.

  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

  Statement (1) implies that if we knew the number of jokers, the answer would be clear: take the cards that are not jokers and divide them by 3 to get the number of red cards. Statement (2) is not clear enough, the number of jokers is not distinct, therefore more data is needed and the two statements taken together are not sufficient.

• Question 178:

  The junior soccer team is one of the best teams in the state of Alabama. The season is divided into two parts, each part is 4 months. In the first part of the season, the junior soccer team won half of their 32 games. How many games did the team win in the entire season?

  (1)

  In the second part of the season, the team lost 9 games, tied 6 games and won 18 games.

  (2)

  From the 32 games remaining the team won twice as much as she lost.

  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 statement (1) we can complete the missing data, in the first part of the season the team won 16 games and on the second part of the season, the team won 18 games. This statement is sufficient enough to answer the question. Statement (2) is not sufficient by it self, it doesn't mention how many games were tied, therefore only statement (1) is sufficient.

• Question 179:

  What is the ratio between W and Q?

  (1)

  Q + W = 23.

  (2)

  W is 25% of Q.

  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: B

  We are looking for Q/W. From statement (1) we know the sum of the two variables, which is not helpful in our case. From statement (2) we know that W = (0.25)Q, therefore we know the ratio between the two variables.

• Question 180:

  What is the product of X and Y?

  (1)

  2X + 2Y = 46.

  (2)

  (X + Y)2 = (X -Y)2 + 8.

  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.

  E.

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

  Correct Answer: B

  The product of X and Y is XY.

  Statement (1) implies only about their sum.

  Statement (2) can be written as: X2 + 2XY +Y2 = X2 ?2XY + Y2 + 8 4XY = 8 XY = 2.

  Only statement (2) is sufficient.
