Meera runs a small online vintage-watch reselling business through a niche marketplace app. Over the course of one month, she acquired five different watches -- Chrono, Aqua, Retro, Classic, and Sport -- at cost prices of Rs. 4,000, Rs. 6,000, Rs. 5,000, Rs. 8,000, and Rs. 3,000 respectively. To stay competitive, she marks up each watch over its cost price before listing it: Chrono by 25%, Aqua by 20%, Retro by 30%, Classic by 15%, and Sport by 40%.

When it came time to sell, Meera offered a discount off the marked price on some of the watches to attract buyers quickly: a 10% discount on the Chrono, a 15% discount on the Aqua, a 25% discount on the Classic, and a 5% discount on the Sport. The Retro was the most sought-after piece in her collection, so she sold it at the full marked price without any discount -- however, since this particular sale went through a premium marketplace listing, the platform charged her a commission of 8% on the selling price of the Retro, which was deducted before the amount was credited to her account.
