where did you get 7*n + 3 ?
is there some other formulas are there like this on different divisible contents ? please tell us what are they ?
excellent and thanks

The simplest way is that if any number that satisfies this condition has to be of the form 7*n + 3
So we need to satisfy one more condition 7*n + 3 has to be less than 100
If 7*n + 3 = 100 then n = 13.8
So the answer is 14 if you consider the number 3 as one of them.

There isn't much special to it at all..
If a number "m" is divisible by 7 then it can be written as 7*n obviously because it's a multiple of 7. So always the number (7*n + 3) will have a remainder of 3.

In general when "m" & "n" are positve and when "m" gets divided by "n" the modulo (m mod n) is the remainder.
For eg: 13 mod 5 = 3 because 13 divided by 5 leaves a remainder of 3
5 mod 3 is 2 because 5 divided by 3 leaves a remainder of 2
