​

Answer 1

Answer:

3050

Step-by-step explanation:

he integers, which are divisible by both 2 and 5, are 10, 20, … 100. This also forms an A.P. with both the first term and common difference equal to 10. Thus, the sum of the integers from 1 to 100, which are divisible by 2 or 5, is 3050.

Answer 2

Answer:

The integers, which are divisible by both 2 and 5, are 10, 20, … 100. This also forms an A.P. with both the first term and common difference equal to 10. Thus, the sum of the integers from 1 to 100, which are divisible by 2 or 5, is 3050.
