If you read it carefully you can easily conclude that half of the goods were sold. So, if the total cost of Goods bought by the trader was $10,000, then what will be the cost of the goods he sold. He actually sold half of the goods, so definitely the cost of goods he sold will be $5,000.
At what amount the trader sold half of the goods he bought. It is given in the accounting quiz that the sales amount was $7,500.
