Each employee of a certain company is in either Department X or Department Y, and there are more than twice as many employees in Department X as in Department Y. The average (arithmetic mean) salary is $25,000 for the employees in Department X and $35,000 for the employees in Department Y. Which of the following amounts could be the average salary for all of the employees of the company? Indicate all such amounts. A. $26,000 B. $28,000 C. $29,000 D. $30,000 E. $31,000 F. $32,000 G. $34,000 Source: https://www.ets.org/content/dam/ets-org/pdfs/gre/gre-sample-questions.pdf

A certain jar contains 60 jelly beans — 22 white, 18 green, 11 yellow, 5 red, and 4 purple. If a jelly bean is to be chosen at random, what is the probability that the jelly bean will be neither red nor purple? A. 0.09 B. 0.15 C. 0.54 D. 0.85 E. 0.91 Source: https://www.ets.org/content/dam/ets-org/pdfs/gre/gre-sample-questions.pdf

D. 0.85 Since there are 5 red and 4 purple jelly beans in the jar, there are 51 that are neither red nor purple and the probability of selecting one of these is (51/60) Since all of the answer choices are decimals, you must convert the fraction to its decimal equivalent, 0.85

y= 2x^2 + 7x - 3 Quantity A: x Quantity B: Y A. Quantity A is greater. B. Quantity B is greater. C. The two quantities are equal. D. The relationship cannot be determined from the information given

Lionel is younger than Maria. Quantity A: Twice Lionel's age Maria's age Quantity B: Maria's age A. Quantity A is greater. B. Quantity B is greater. C. The two quantities are equal. D. The relationship cannot be determined from the information given. Source: https://www.ets.org/content/dam/ets-org/pdfs/gre/gre-sample-questions.pdf

D. The relationship cannot be determined from the information given. If Lionel's age is 6 years and Maria's age is 10 years, then Quantity A is greater, but if Lionel's age is 4 years and Maria's age is 10 years, then Quantity B is greater. Thus, the relationship cannot be determined

Quantity A: The least prime number greater than 24 Quantity B: The greatest prime number less than 28 A. Quantity A is greater. B. Quantity B is greater. C. The two quantities are equal. D. The relationship cannot be determined from the information given. Source: https://www.ets.org/content/dam/ets-org/pdfs/gre/gre-sample-questions.pdf

Quantity A is greater For the integers greater than 24, note that 25, 26, 27 and 28 are not prime numbers, but 29 is a prime number, as are 31 and many other greater integers. Thus, 29 is the least prime number greater than 24, and Quantity A is 29. For the integers less than 28, note that 27, 26, 25, and 24 are not prime numbers, but 23 is a prime number, as are 19 and several other lesser integers. Thus, 23 is the greatest prime number less than 28, and Quantity B is 23
