Mr. Charles bought 10 high tech laptops for $1000 when he travelled to the US. That means each of the laptops cost him $100. On getting back to Nigeria, he spoke with few people about the laptops and how much he was willing to sell each of them. After bargaining and all, he sold each laptop at the rate of $300. Is it right for Mr. Charles as a believer to sell the laptops at 3 times the price he got them in the name of business?
