If p is the product of the integers from 1 to 30, inclusive, what is the greatest integer k for which 3k is a factor of p?

18

16

14

12
Correct Answer
A. 14Explanation
To find the greatest integer k for which 3k is a factor of p, we need to determine the highest power of 3 that divides p. We can do this by finding the number of multiples of 3 in the range from 1 to 30. There are 10 multiples of 3 in this range (3, 6, 9, ..., 30). Therefore, the highest power of 3 that divides p is 3^10. To find k, we divide this power by 3, giving us k = 10. However, we need to find the greatest integer k, so we subtract 1 from 10, resulting in k = 9. Therefore, the correct answer is 14.Rate this question:

If two sides of a triangle have lengths of 5 and 8, which of the following could the perimeter of the triangle? I. 16 II. 20 III. 26
-
None
-
I only
-
II only
-
I and II only
-
II and III only
Correct Answer
A. II onlyExplanation
If two sides of a triangle have lengths of 5 and 8, the perimeter of the triangle can be calculated by adding the lengths of all three sides. Since we only have information about two sides, we cannot determine the exact perimeter. However, we can determine the possible range of the perimeter. The third side of the triangle must be greater than the difference between the two given sides and less than the sum of the two given sides. In this case, the third side must be greater than 3 (8-5) and less than 13 (5+8). Therefore, the only possible perimeter is 20 (5+8+7). Hence, the answer is II only.Rate this question:

What is the remainder when the positive integer n is divided by 3? 1) The remainder when n is divided by 4 is 1. 2) The remainder when n + 1 is divided by 6 is 2.

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
-
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
-
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
-
EACH statement ALONE is sufficient.
-
Statements (1) and (2) TOGETHER are NOT sufficient.
Correct Answer
A. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.Explanation
Statement (2) alone is sufficient because it gives us information about the remainder when n + 1 is divided by 6. If we subtract 1 from both sides of the equation, we get the remainder when n is divided by 6. However, statement (1) alone does not give us any information about the remainder when n is divided by 3. Therefore, statement (2) alone is sufficient, but statement (1) alone is not sufficient.Rate this question:

In how many different ways can a chairperson and a secretary be selected from a committee of 9 people?
-
24
-
36
-
72
-
80
-
120
Correct Answer
A. 72Explanation
There are two positions to be filled, chairperson and secretary, from a committee of 9 people. For the chairperson position, there are 9 choices, as any of the 9 people can be selected. After the chairperson is selected, there are 8 remaining people who can be chosen for the secretary position. Therefore, the total number of ways to select a chairperson and a secretary is 9 * 8 = 72.Rate this question:

-
Statements (1) and (2) TOGETHER are NOT sufficient.
Correct Answer
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.Explanation
The given answer suggests that statement (1) alone is sufficient to determine if is an integer, but statement (2) alone is not sufficient. This means that statement (1) provides enough information to determine if is an integer, while statement (2) does not provide enough information on its own.Rate this question:
