What is the value of `m-n+37` ?
I. m is the largest possible six-digit number and n is the smallest possible six-digit number.
II. The difference between m and n is known.

Answer

To solve the question "What is the value of `m - n + 37`?", we will analyze both statements provided.

### Step 1: Analyze Statement I
- **Statement I** states that `m` is the largest possible six-digit number and `n` is the smallest possible six-digit number.
- The largest six-digit number is `999999` (which means `m = 999999`).
- The smallest six-digit number is `100000` (which means `n = 100000`).

### Step 2: Calculate `m - n + 37`
- Now we can substitute the values of `m` and `n` into the expression:
\[ m - n + 37 = 999999 - 100000 + 37 \]
- First, calculate `999999 - 100000`:
\[ 999999 - 100000 = 899999 \]
- Now, add `37` to `899999`:
\[ 899999 + 37 = 900036 \]

### Conclusion from Statement I
- From Statement I, we find that the value of `m - n + 37` is `900036`.
- Therefore, Statement I is sufficient to answer the question.

### Step 3: Analyze Statement II
- **Statement II** states that the difference between `m` and `n` is known.
- However, it does not provide specific values for `m` or `n`. Knowing the difference alone does not allow us to determine the exact values of `m` and `n`, and thus we cannot compute `m - n + 37`.

### Conclusion from Statement II
- Statement II is not sufficient to answer the question.

### Final Answer
- Based on the analysis, the answer is that Statement I alone is sufficient, while Statement II is not sufficient.
