Baljeet, with his parents, wants to buy a local franchising hub. He found an interesting building which will cost her 40,000 rupees every beginning of each quarter increasing by 6% every quarter for 5 years. However, after paying for 3 years, he decided to stop because he got in an argument with his parents. How much money does he still owe (remaining balance) at the end of 3 years? If he wanted to continue the payment of 50,000 rupees every end of each year after the last payment, how long would it take for him to take ownership of the building?
