The sum of intergers from `1` to `100` that are divisible by `2` or `5` is -A. `2550`B. `1050`C. `3050`D. `4150`

Answer» Correct Answer - C
Sum of integers divided by `2`
`= 2 + 4 + 6 + 8 +"….."+100 = 50 xx 51 = 2550`
Sum of integers divided by `5` ltbRgt `= 5 + 10 + 15 +"….."+ 100 = 51 xx 20 = 1050`
Sum of intergers divided by `10`
`= 10 + 20 +"….."+ 100 = 550`
`:.` Required sum `= 2550 + 1050 - 550 = 3050`
