• Question 111:

  How many Popsicles can Amy and Megan eat in 30 minutes?

  (1)

  Megan eats twice as fast as Amy.

  (2)

  Megan can eat 5 more Popsicles than Amy in 15 minutes.

  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

  Statement (1) is insufficient by itself because it only gives us the ratio between the two and we need a concrete number, which statement (2) provides. Altogether we have two equations with two unknowns and the solution is feasible by using both statements.

• Question 112:

  A new taxi service charges money according to the weight of the passengers and their luggage or according to the distance they wish to travel. If the taxi service charges the highest among the two, according to what will the Smith's pay, weight or distance?

  (1)

  The total weight of the Smith's family including the luggage is 300 Kg.

  (2)

  The total distance, which the Smith's wish to travel is 100 Km.

  A.

  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 are given two possibilities of charging fee, according to two different criteria's but both statements don't

  provide us with the conversion factor from weight to amount of money or from distance to amount of

  money.

  More sufficient data is required.

• Question 113:

  Two giant identical poles have been planted in the ground. One of the poles was planted dipper than the other pole. The shadow of pole A is 10 meters long and the shadow of pole B is 8 meters long. How tall is pole B?

  (1)

  Pole A is hoisted 14 meters in the air.

  (2)

  Pole B is located 2 meters from pole A.

  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

  The shadows are proportioned to their height. Statement (1) gives us the height of pole A and so by using the proportion we can calculate the height of pole B. The proportions are 10/14 = 8/Hb, from that we know the height of pole B. Statement (2) is insufficient because the distance between the poles is irrelevant to the question and it doesn't contribute anything.

• Question 114:

  How long exactly did it take Claudia to drive from the beach house to her green house?

  (1)

  Claudia drove at a constant speed of 55 miles per hour.

  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 are specifically asked about the exact time and not an approximation. Statement (1) gives us the exact

  traveling speed of Claudia. Statement (2) gives us the approximate distance between the two houses and

  therefore we can only calculate the approximate duration and not the exact one.

  More accurate data is required.

• Question 115:

  How many pictures exactly did Sammy develop on Saturday?

  (1)

  Sammy gave away 3 films for development.

  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

  The question asked explicitly for an exact number of pictures. Statement (1) is not sufficient by itself because it gives us no data on the pictures. Statement (2) completes statement (1) but not accurately as the question required and therefore more sufficient or accurate data is required.

• Question 116:

  What is the average number of questions that Laura can write in three days if on the first day she wrote 20 questions?

  (1)

  Every passing day the number of questions that Laura writes grows by 20%.

  (2)

  On the other two days, Laura wrote 53 questions.

  A.

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

  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

  Laura writes questions over a 3 day period.

  In the first day Laura wrote 20 questions.

  Statement (1) tells us that on the second day she wrote (1.2 x 20 = 24) questions and on the third day she

  wrote (1.2 x 24). This statement is sufficient in order to calculate the average. Statement (2) is also

  sufficient, it gives us the sum of questions that Laura wrote in the other 2 days and therefore the average

  can be easily calculated.

  Each statement is sufficient on its own.

• Question 117:

  How much time will it take two different fire extinguishers to shut down a level 3 fire?

  (1)

  The first fire extinguisher can shut down a level 3 fire in 45 seconds.

  (2)

  The second fire extinguisher can shut down a level 3 fire in one minute and 20 seconds.

  A.

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

  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

  Statement (1) gives you the output of the first fire extinguisher, which is 1/45 fires in a second. Statement

  (2) gives you the output of the second fire extinguisher, which is 1/110 fires in a second. Combine the two statements, we know the total output of the two extinguishers and so we can easily calculate the time it would take them to shut down the fire.

• Question 118:

  How much time will it take Gus to deliver 350 newspapers on his bikes?

  (1)Tom and Gus, working together each on his bike, can deliver 100 newspapers in one hour.

  (2)Tom

  can deliver 25 newspapers in 30 minutes on Gus's bike.

  A.

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

  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) gives us the output of Gus and Tom, together, in order to answer the question we need to know the output of Tom on his bike alone. Statement (2) gives us almost that, it gives us the output of Tom on Gus's bike and as far as we are concerned, his bike could be a lot faster or slower and thus the output will change accordingly. More sufficient data is required.

• Question 119:

  How long will it take Jim to wax his car?

  (1)

  It would take Jim and Mike 40 minutes to wax Jim's car.

  (2)

  It would take Mike 1 hour and 20 minutes to wax his car.

  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) gives us the output of Jim and Mike together on Jim's car only. Statement (2) gives us Mike's output on his car and not Jim's car and therefore we can't conclude anything about the output of Mike on Jim's car. More sufficient data is required.

• Question 120:

  What is the value of (X + Y)/X?

  (1)

  Y is 35% more than X.

  (2)

  Y = 88.

  A.

  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

  The expression can be written as: (X + Y)/X = 1 + Y/X and therefore we need the ratio only. Statement (1) is sufficient because it gives us the ratio between Y and X, Y = 1.35X. Statement (2) is insufficient by itself since it supplies no data on the variable X.
