Passage

Harsh runs a store where he sells various items. He bought a batch of 100 mobile phones at a cost of ₹10,000 each. To clear his stock, he offered a discount of 20% on the selling price, which is set at ₹15,000 per phone. However, he noticed that the phones were selling slowly, so he increased the discount to 30%, which led to an increase in sales. On the other hand, Harsh also invested ₹200,000 in a fixed deposit at an interest rate of 10% per annum, compounded annually. This deposit was made three years ago. Additionally, Harsh employs two workers in his store. One worker can complete a task in 10 hours, while the other can do the same task in 15 hours. They both work together for 6 hours and then the first worker leaves, leaving the second worker to complete the remaining task.
