陳生有件貨品,成本$18,標價$21,
有一名客人拎張$100同佢買,
陳生無散紙,就去搵個街坊唱散佢,
點知後來發現個客人張$100係假既,
陳生只好俾過張$100街坊,
請問係呢次交易裡面,陳生損失左幾多錢呢?
My philosophy is that there is no greater elegance than simplicity.
1 CPU in a computer is preferred over 2.
1 girlfriend is preferred over a few.
1 credit card is preferred over many.
The elimination of bloat from surroundings is the key to successful life in a simple, neat, clean and efficient manner.
