If m and n are integers, is m odd??1) m + n is odd... more2) m + n = n...
(1) n + m is odd
The sum of two integers is odd only if one is odd and another is even, hence m may or may not be odd. Not sufficient.
(2) n + m = n2 + 5
--> m−5=n2−n
=> m−5=n(n−1)
either n or n−1 is even hence n(n−1)=even
=> n(n−1)=even
=> m−5=m−odd=even
--> m=odd. Sufficient.

If m and n are integers, is m odd??1) m + n is odd... more2) m + n = n...
Statement 1: m + n is odd
Statement 2: m * n = n^2 + 5
To determine if m is odd, we need to evaluate both statements together.
Explanation:
To determine if m is odd, we need to examine the given statements in more detail.
Statement 1: m + n is odd
This statement tells us that the sum of m and n is odd. However, it does not provide any specific information about m or n individually. Therefore, we cannot determine if m is odd based on this statement alone.
Statement 2: m * n = n^2 + 5
This statement tells us that the product of m and n is equal to n^2 + 5. Again, this does not provide any specific information about m or n individually. Therefore, we cannot determine if m is odd based on this statement alone.
Combining the Statements:
By combining the two statements, we can potentially gather more information to determine if m is odd.
From statement 1, we know that m + n is odd. If we substitute n^2 + 5 for m * n (from statement 2), we get:
n^2 + 5 + n is odd
Simplifying further, we have:
n(n + 1) + 5 is odd
Since the sum of two odd integers is always even, we can conclude that n(n + 1) must be odd. This means that either n or (n + 1) must be odd.
However, this does not provide us with enough information to determine if m is odd. We still don't know the individual values of m or n.
Conclusion:
Based on the given information, we cannot definitively determine if m is odd. Therefore, more information is required to answer the question. The correct answer is option 'D'.
If m and n are integers, is m odd??1) m + n is odd... more2) m + n = n...
The question here is not much clear. But I think the answer is A.
Stat 1 : m+n is odd => either m is odd or n is odd. (can't answer)
Stat 2 : m+n = n^2 + 5 => m - 5 = n^2 - n = n*(n-1) which is even, on all n values
=> m-5 = even
=> m = even +5
=> m = odd. (can answer)
Exactly one of the statements can answer.
Option A
