Consider a money lender who lends money ...

Consider a money lender who lends money on interest. We observe that if he lends more money on a certain rate of interest, the interest earned will be more. In other words, if the money invested increases, the interest earned also increases and vice-versa. Thus, the money invested and the interest earned on it are in direct variation.
