Sonia owns a boutique and has invested ₹600,000 in the initial setup. She sells designer dresses, marking up the prices by 40%. During a festive season, she offers a 20% discount on all items. Sonia also invested ₹200,000 in a savings account with an interest rate of 8% per annum, compounded annually. Additionally, she has employed two tailors to manage the production. The first tailor can stitch 5 dresses in 10 hours, while the second tailor can stitch 5 dresses in 15 hours. They work together for 4 hours a day and then the first tailor continues to work alone for the rest of the day. Sonia plans to sell a batch of 50 dresses.
