 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that how much will $25,000 amount to in 3 years compounded yearly if the rate for successive years are 6%, 8% and 10% respectively. Now we know that amount is equal to P into 1 plus R upon 100 raised to the M. If rate of interest for successive years is different R1, R2 and R3 for first year, second year and third year respectively. Then amount after 3 years is equal to P into 1 plus R1 upon 100 into 1 plus R2 upon 100 into 1 plus R3 upon 100. With this key idea let us proceed with the solution. According to the question we need to find the amount after 3 years for a principal of $25,000 at the rate of 6%, 8% and 10% for successive years. So here the principal P is equal to $25,000, time is equal to 3 years and the rate of interest R1 is equal to 6% for the first year. R2 is equal to 8% for the second year and R3 is equal to 10% for the third year. As we know amount after 3 years will be A is equal to P into 1 plus R1 upon 100 into 1 plus R2 upon 100 into 1 plus R3 upon 100. That is amount A is equal to 25,000 into 1 plus 6 upon 100 into 1 plus 8 upon 100 into 1 plus 10 upon 100. Taking the assume within the brackets we have this is equal to 25,000 into 100 plus 6 upon 100 into 100 plus 8 upon 100 into 100 plus 10 upon 100. Which is equal to 25,000 into 106 upon 100 into 108 upon 100 into 110 upon 100. First cancelling the zeros 25 into 4 is 100, 2 into 53 is 106 and 2 into 54 is 108. This is equal to 53 into 54 into 11 which is equal to 31,482 dollars. Hence the amount after 3 years is equal to 31,482 dollars which is our answer. This completes our session. Hope you enjoy this session.
