A shopkeeper buys a used laptop for \(Rs.\)15533 and a used desktop for \(Rs.\)37691. He spends \(Rs.\)836 on repair for the laptop and \(Rs.\)835 on repair for the desktop. If he had marked the price as \(Rs.\)29918 and \(Rs.\)65920 respectively and offers a discount of \(Rs.\)9911 on each of them, find the profit or loss incurred.
