If n is an integer, then n is divisible by how many positive integers?
(1) n is the product of two different prime numbers.
(2) n and 23 are each divisible by the same number of positive integers.
  • a)
    Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked
  • b)
    Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked
  • c)
    BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient
  • d)
    EACH statement ALONE is sufficient to answer the question asked
  • e)
    Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed
Correct answer is option 'D'. Can you explain this answer?

If n is an integer, then n is divisible by how many positive integers?...
Statement (1): n is the product of two different prime numbers.
If n is the product of two different prime numbers, then n can be expressed as the product of p and q, where p and q are distinct prime numbers. In this case, n has two distinct prime factors. Since n is an integer, it must also be divisible by 1 and itself. Therefore, n is divisible by at least four positive integers.
Statement (2): n and 23 are each divisible by the same number of positive integers.
This statement tells us that the number of positive divisors of n is the same as the number of positive divisors of 23. Since 23 is a prime number, it has exactly two positive divisors: 1 and 23. If n has the same number of positive divisors as 23, it means that n is also a prime number and has exactly two positive divisors: 1 and itself. Therefore, n is divisible by exactly two positive integers.
From the evaluation of both statements, we can see that each statement alone is sufficient to answer the question. Statement (1) tells us that n is divisible by at least four positive integers, and Statement (2) tells us that n is divisible by exactly two positive integers. Therefore, the answer is (D) EACH statement ALONE is sufficient to answer the question asked.

If n is an integer, then n is divisible by how many positive integers?...
Statement (1): n is the product of two different prime numbers.
- If n is the product of two different prime numbers, then n can be expressed as p*q, where p and q are distinct prime numbers.
- The number of positive integers by which n is divisible can be determined by finding the number of factors of n.
- The number of factors of n can be calculated by finding the product of the exponents of each prime factor and adding 1 to each exponent, and then multiplying the results.
- For example, if n = p^a * q^b, where p and q are prime numbers and a and b are positive integers, then the number of factors of n is (a+1)*(b+1).
- Therefore, statement (1) alone is sufficient to determine the number of positive integers by which n is divisible.

Statement (2): n and 23 are each divisible by the same number of positive integers.
- This statement does not provide direct information about the factors of n.
- It only states that the number of positive integers by which n is divisible is the same as the number of positive integers by which 23 is divisible.
- However, this information is not sufficient to determine the exact number of positive integers by which n is divisible.
- Therefore, statement (2) alone is not sufficient to determine the number of positive integers by which n is divisible.

Combined statements:
- Combining both statements, we know that n is the product of two different prime numbers (statement 1) and the number of positive integers by which n is divisible is the same as the number of positive integers by which 23 is divisible (statement 2).
- Since 23 is a prime number, it is only divisible by 1 and itself, so it has 2 positive divisors.
- Therefore, the number of positive integers by which n is divisible is also 2, as stated in statement 2.
- Hence, both statements together are sufficient to determine that n is divisible by 2 positive integers.
- Therefore, the correct answer is option D.
