1. Brian is dividing 50 marbles into 3 groups. How many marbles are in the largest of the three groups?
(1) The sum of the two smaller groups of marbles is equal to the largest group of marbles.
(2) The smallest group contains 6 marbles
A. Statement (1) ALONE is sufficient, but statement (2) is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient
A
The first statement establishes that the larger group constitutes half of the total amount of marbles, which means it must be equal to 25 marbles.
2. Manu and Joby each received a salary increase. Which one received the greater dollar increase?
(1) Manu salary increased 8 percent.
(2) Joby salary increased 5 percent.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. Statements (1) and (2) TOGETHER are NOT sufficient.
D
In (1) there is no information about joby salary and in (2) there is no information about manu salary; thus neither statement alone is sufficient, and the answer must thethird or fifth choice. Since (1) and (2) together give only the percentage increases insalary, it cannot be determined which person received the greater dollar increase.Therefore, (1) and (2) together are not sufficient, and the best answer is the last choice.
3. Is the perimeter of a given rectangle greater than 8 inches?
(1) The two shorter sides of the rectangle are 2 inches long.
(2) The length of the rectangle is 2 inches greater than the width of the…..
A. Statement (1) ALONE is sufficient, but statement (2) is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
A
Statement (1) ALONE is sufficient, but statement (2) is not sufficient.
4. What is the average test score of Angela, Barry, Carl, Dennis, and Edward?
(1) The average of the test scores of Barry, Carl, and Edward is 87.
(2) The average of the test scores of Angela and Dennis is 84.
A. Statement (1) ALONE is sufficient, but statement (2) is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
C
As long as the sum of all five test scores can be calculated, it will be possible to calculate the average score.
5. The symbol ? represents one of the following operations: addition, subtraction,multiplication, or division. What is the value of 3 ? 2 ?
(1) 0 + 1 = 1
(2) 1 – 0 = 1
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient
A
Since 0 + 1 = 1, 0 – 1 = -1, 0 × 1 = 0, and 0 ÷ 1 = 0, it follows from (1) that ? represents addition, so the value of 3 ? 2 can be determined. Hence, (1) alone is sufficient.Since 1 + 0 = 1, 1 – 0 = 1, 1 × 0 = 0, and 1 ÷ 0 is undefined, it follows from (2) that ? could represent either addition or subtraction, so that 3 ? 2 could equal 5 or 1. Thus, (2) alone is not sufficient. The best answer is the first choice
