Question

find sum of odd multiples of 3 digit numbers divisible by 7​

Answer 1

Step-by-step explanation:

The first and also the smallest 3 digit number is 100.

To find the first 3 digit number divisible by 7, we divide the very first 3 digit number 100 by 7

100/7 = 14.29

We have decimal in the result of 100/7.

Clearly the first 3 digit number 100 is not exactly divisible by 7.

Let us divide the second 3 digit number 101 by 7.

101/7 = 14.43

We have decimal in the result of 101/7 also.

So, the second 3 digit number 101 is also not exactly divisible by 7
