    That is not enough information to answer the question. You need to know how much the shopkeeper paid for the merchandise and what his original selling price was.
    Example:
    Shopkeeper buys digglydoos for $1 each and sells them for $2 each. This is a 200% return, meaning that the keeper got back twice as much money as he put in.
    If he sold them for a 20% discount, he would be selling them for $1.60 each and making a 160% return, which would be a profit of $0.60 instead of $1.00.
