​

Answer 1

Answer:

3050 is the answer

Step-by-step explanation:

Find the sum of integers from 1 to 100 that are divisible by 2 or...

1. The integers from 1 to 100, which are divisible by 5, are 5, 10… 100. ...
2. The integers, which are divisible by both 2 and 5, are 10, 20, … 100. ...

∴Required sum = 2550 + 1050 – 550 = 3050. Thus, the sum of the integers from 1 to 100, which are divisible by 2 or 5, is 3050.
