一天有個年輕人來到王老闆的店裏買了一件禮物,這件禮物成本是18元,標價是21元.結果是這個年輕人掏出100元要買這件禮物,王老闆當時沒有零錢,用那100元向街坊換了100元的零錢,找給年輕人79元.但是街坊後來發現那100元是假鈔,王老闆無奈還了街坊100元.現在問題是: 王老闆在這次交易中到底損失了多少錢?? Translate myself: One day, a young man buy a present in a shop, the original cost of the present is Rm18, and the price tags is Rm21. The young man paid Rm100 to the shopkeeper. Due to shortage of (small) money, the shopkeeper change the money with his neighbour, and then return back Rm79 to the young man. But later, his neighbour found out that the Rm100 just now is a fake note and request the shopkeeper to return real Rm100 to him, and the shopkeeper did so. The question now is , how much the shopkeeper has lost in the trading ? Edited:SHOW YOUR CALCULATIONS! |
