• Question 131:

  Derrick is flying a small Cessna light plane for 2 hours. What is Derrick's average flying speed in miles per hour?

  (1)

  Derrick flew 250 miles.

  (2)

  Derrick's top speed was 200 miles per hour and his low speed was 100 miles 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: A

  The average flying speed can be found by dividing the total distance by the total time. Statement (1) gives

  us the total distance and the total flying time is given to us in the question and therefore this statement is

  sufficient.

  Statement (2) is irrelevant, the changes in velocities during the time interval don't affect the average speed.

  And therefore this statement is insufficient.

• Question 132:

  Did the average cost of flying abroad decline this year?

  (1)

  If the geo-political situation in the area is evolving, the average cost of flying abroad declines.

  (2)

  The geo-political situation in the area is not evolving, yet more people fly this year than the previous years.

  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) gives us a link between the cost of flying abroad and the geo-political situation. Statement

  (2) tells us the geo-political situation and thus we know the changes in the average cost of flying abroad.

  The second piece of information given in statement (2) is irrelevant, we are not told about a connection

  between the number of people and the price of flying abroad.

  Both statements, taken together, are sufficient.

• Question 133:

  Did the value of the house grow this year?

  (1)

  If the neighborhood becomes more crowded the value of the house drops.

  (2)

  This year the neighborhood has gotten less crowded yet a new railway was built nearby.

  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) gives a casual link between the value of the house and the neighborhood, yet no data on the neighborhood was given in this statement. Statement (2) tells us that the neighborhood has gotten less crowded and so the value of the house grew. Statement (2) also tells us about a new railway that was built nearby but no link has been given to us about the connection between the value of the house and the rails. Both statements, taken together are sufficient.

• Question 134:

  There is a traffic jam in the freeway, is the number of cars getting bigger by the minute?

  (1)

  25 cars escape the traffic by exiting the freeway at the nearest exit every minute.

  (2)

  40 new cars get stuck in the traffic jam every two 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) tells us the rate at which people are getting out of the traffic jam, but we need to know if anyone is joining the line to be able to answer the question. STATEMENT (2) gives us this information. Therefore the two together are sufficient to see that the net gain in number of cars on the line is 5 per minute; the number of cars is getting smaller.

• Question 135:

  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) tells us the rate at which people are getting out of the line, but we need to know if anyone is joining the line to be able to answer the question. STATEMENT (2) gives us this information. Therefore the two together are sufficient to see that the net gain in people on the line is 2 per minute; the line is getting shorter.

• Question 136:

  E.

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

  Correct Answer: E

  STATEMENTS (1) and (2) together are insufficient. You need to know whether the wages of the average worker changed. 10 minutes of work last year could be worth more or less than 8 minutes today.

• Question 137:

  A television set cost $65 in 1981, did it cost more than $65 in 1983?

  E.

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

  Correct Answer: E

  STATEMENTS (1) and (2) together are insufficient. You need to know whether the wages of the average family changed. 3 weeks of work in 1981 could be worth more or less than 2 weeks of work in 1983. More sufficient data is required.

• Question 138:

  One cubic centimeter is equal to 0.001 liters, is a volume of a rectangular tank larger than 0.001 liters?

  (1)

  The rectangular tank holds 0.3 teaspoons. There are 0.0049 liters in one teaspoon.

  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) gives us the amount of teaspoons that the tank holds and it gives us that conversion between teaspoons and liters. This statement is sufficient. Statement (2) is also sufficient since we are given the dimensions of the tank, we can calculate the volume and compare it to the volume of one cubic centimeter.

• Question 139:

  If a full glass of water holds 0.236 liters, how many liters are there in one pint?

  (1)

  One pint is 1/8 of a gallon.

  (2)

  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 data about the glass of water is irrelevant, all you're asked is how many liters are there in a pint.

  Statement (1) is insufficient because we are told the conversion from pint to gallons only. Statement (2) is

  insufficient because we are told the conversion from gallons to liters only and we have no connection to

  pints.

  Combine both statements so you know how many gallons is one pint and how many liters are in 1/8 of a

  gallon. Both statements taken together are sufficient.

• Question 140:

  How much was the original price of a car, which was sold for $25,000?

  E.

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

  Correct Answer: B

  Statement (1) is insufficient since it doesn't give us exact information about the original price, more than half is not accurate enough. Statement (2) is sufficient since it tells us that the original value is 65% of the price it was sold.
