 Hello and welcome to the session, let's work out the following problem. It says A plans to buy a new flat after 5 years which will cost him Rs. 552,000. How much money should he deposit annually to accumulate this amount if he gets in trust 5% per annum compounded annually. So let's now move on to the solution and let man deposits Rs. X per annum per year and after 5 years cost of flat will be Rs. 552,000. Now principle is given by the formula A into 1 plus I to the power n minus 1 upon I where A is the amount, P is the principle I is the rate of interest which is given to be 5%. The number of years which is given to be 5 years. So now the principle after 5 years will be 552,000 and X is the amount which deposits every year. So it is X into 1 plus I which is 0.05 to the power 5 minus 1 upon 0.05. So this implies X is equal to 552,000 into 0.05 it is same as 5 upon 100 upon 1 plus 0.05 is 1.05 to the power 5 minus 1. Now 2 zeros gets cancel and we have 552,000, 5,520 into 5 upon 1.05 to the power 5 is given to be 1.276 minus 1 which is again equal to 27,600 upon 0.276 which is equal to 1 lakh hence the man deposit rupees 1 lakh. So this completes the question and the session why for now take care and have a good day.
