Find the number of positive integers greater than 6000 and less than 7000 which are divisible by 5, provided that no digit is to be repeated.

Explanation

To solve the problem of finding the number of positive integers greater than 6000 and less than 7000 that are divisible by 5, with the condition that no digit is repeated, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Range**:
We are looking for numbers between 6000 and 7000. This means the first digit (thousands place) must be 6. Therefore, our number will be of the form 6XXX, where X represents the other digits.

2. **Determine the Units Digit**:
