welcome to the lecture on problem solving based on interest formulas so in this lecture we will try to solve problems numerical problems based on the factors of Interest what we have so far studied and try to solve it let us see the first example there is a problem which tells that a person 35

year old is planning to invest an equal sum of rupees 10,000 at the end of every year for the next 25 years starting from the end of the next year the bank gives 20% interest rate compounded annually what amount will he get when he will be 60 years old so as it indicates

basically we are going to discuss all the problems based on equal payment series factors or uniform series factors we have already solved one problem based on single payment series present worth factor and single payment series compound amount Factor so we will discuss the problems based on equal payment series or uniform series Factor

now let us see in this problem basically a person is investing 10,000 rupees equal sum at the end of every year year end is so it means in this problem a is given given a that is year end payment and this is given as 10,000 then this amount he is depositing for the next 25 years starting from the

end of the first year and the bank is giving 20% interest rate so I is 20% that is 0.2 your since he is going to have the amount when he is 60 years old so anyway he is going to deposit this amount for 25 years and that is why your interest periods are
