Pretty easy challenge, it requires no math skills (modulo operator couldn't be considered serious math at all). It shows how person can do basic things.
There are plenty of real life tasks that look like this, for example, getting some resultset from db and transforming results in loop by some criteria (i.e. several if's in loop). I don't think that programmer with any experience may have problems with that.
