Find the
(i) sum of those integers between 1 and 500 which are multiples of 2 as well as of 5.
(ii) sum of those integers from 1 to 500 which are multiples of 2 as well as of 5.
(iii) sum of those integers from 1 to 500 which are multiples of 2 or 5.

Explanation

To solve the given problem, we will break it down into three parts as specified in the question.

### Part (i): Sum of integers between 1 and 500 which are multiples of both 2 and 5.

1. **Identify the common multiple of 2 and 5**:
The least common multiple (LCM) of 2 and 5 is 10. Therefore, we need to find the multiples of 10 between 1 and 500.

2. **Determine the sequence of multiples of 10**:
