Quantitative Techniques Section 2

Ravi has recently opened a grocery store. He purchased the initial inventory worth ₹400,000. To attract customers, he decided to mark up the prices by 25% on all items. However, after a month, he realized that some items were not selling well, so he offered a 10% discount on those items. Additionally, Ravi took a loan of ₹250,000 from a bank at an interest rate of 9% per annum, compounded annually, to renovate the store. To manage the store, he hired two assistants. The first assistant can restock the shelves in 4 hours, while the second assistant can do the same in 6 hours. They work together for the first 2 hours each day and then the second assistant works alone for the remaining hours.
