Options

A. 4086
B. 5076
C. 4386
D. 3242

Answer

To find the maximum possible difference between the four-digit numbers formed using the digits 1, 2, 3, and 5, we will follow these steps:

### Step 1: Identify the digits
The digits we can use are 1, 2, 3, and 5.

### Step 2: Form the largest four-digit number
To create the largest four-digit number, we should arrange the digits in descending order. Thus, the largest number we can form is:
- **Largest Number = 5321**

### Step 3: Form the smallest four-digit number
To create the smallest four-digit number, we should arrange the digits in ascending order. Thus, the smallest number we can form is:
- **Smallest Number = 1235**

### Step 4: Calculate the difference
Now, we will find the difference between the largest and smallest four-digit numbers:
- **Difference = Largest Number - Smallest Number**
- **Difference = 5321 - 1235**

### Step 5: Perform the subtraction
Now, we will perform the subtraction:
- 5321
- 1235
- _______
- 4086

### Conclusion
The maximum possible difference between the four-digit numbers formed by using the digits 1, 2, 3, and 5 is:
- **Maximum Difference = 4086**
