Is the positive integer x divisible by 12?(1) x is divisible by 6(2) x...
Evaluate Statement (1) ALONE: x is divisible by 6
Approach: Look for a counter example
Approach: Look for a counter example
Example: x = 6. It is divisible by 6. However, it is NOT divisible by 12.
Counter Example: x = 12. It is divisible by 6. It is divisible by 12 as well.
Knowing that x is divisible by 6 is not enough to answer the question.
Counter Example: x = 12. It is divisible by 6. It is divisible by 12 as well.
Knowing that x is divisible by 6 is not enough to answer the question.
If x is divisible by 6, we can infer that it is divisible by 3 and 2. But we cannot deduce whether it is also divisible by 22 - which is essential to deduce that x is divisible by 12.
Statement 1 ALONE is NOT sufficient.
Eliminate choices A and D. Choices narrow down to B, C, or E.
Eliminate choices A and D. Choices narrow down to B, C, or E.
Evaluate Statement (2) ALONE: x is divisible by 8
If x is divisible by 8, then x will definitely be divisible by 4.
However, from statement (2) alone we do not know if x is divisible by 3.
Alternative Approach: Look for a counter example
If x is divisible by 8, then x will definitely be divisible by 4.
However, from statement (2) alone we do not know if x is divisible by 3.
Alternative Approach: Look for a counter example
Example: x = 8. It is divisible by 8. However, it is NOT divisible by 12.
Counter Example: x = 24. It is divisible by 8. It is divisible by 12 as well.
Knowing that x is divisible by 8 is not enough to answer the question.
Counter Example: x = 24. It is divisible by 8. It is divisible by 12 as well.
Knowing that x is divisible by 8 is not enough to answer the question.
Statement 2 ALONE is NOT sufficient.
Eliminate choice B. Choices narrow down to C or E.
Eliminate choice B. Choices narrow down to C or E.
Evaluate Statements (1) & (2) Together: x is divisible by 6 & x is divisible by 8
From statement 1, if x is divisible by 6, it is definitely divisible by 3.
From statement 2, if x is divisible by 8, it is definitely divisible by 4.
So, by combining the two statements, we can conclude that x is divisible by 3 and by 4.
Or that x is divisible by 12.
From statement 1, if x is divisible by 6, it is definitely divisible by 3.
From statement 2, if x is divisible by 8, it is definitely divisible by 4.
So, by combining the two statements, we can conclude that x is divisible by 3 and by 4.
Or that x is divisible by 12.
Statement TOGETHER are sufficient. Choice C is the answer.

Is the positive integer x divisible by 12?(1) x is divisible by 6(2) x...
Statement 1: x is divisible by 6.
Statement 2: x is divisible by 8.
To determine if x is divisible by 12, we need to check if x is divisible by both 6 and 8.
Analysis of Statement 1:
If x is divisible by 6, it means x can be written as 6k, where k is an integer. However, this does not provide any information about divisibility by 8. Therefore, statement 1 alone is not sufficient to answer the question.
Analysis of Statement 2:
If x is divisible by 8, it means x can be written as 8m, where m is an integer. However, this does not provide any information about divisibility by 6. Therefore, statement 2 alone is not sufficient to answer the question.
Combined Analysis of Statements 1 and 2:
From statement 1, we know that x is divisible by 6, so x can be written as 6k.
From statement 2, we know that x is divisible by 8, so x can be written as 8m.
To determine if x is divisible by 12, we need to find a common multiple of 6 and 8. The least common multiple of 6 and 8 is 24.
We can express x as 6k and 8m, and since 24 is a multiple of both 6 and 8, we can express x as 24n, where n is an integer.
Therefore, both statements together are sufficient to determine that x is divisible by 12.
Conclusion:
Both statements together are sufficient to answer the question, but neither statement alone is sufficient. Therefore, the correct answer is option C.
Statement 2: x is divisible by 8.
