Assume number of digits of your student id represent number of end-of-year payments (cash outflow). Each payment is determined by multiplying each digit of student id by BDT 1,000. For example, if first digit of your student ID is '1', the first end of year payment will be BDT 1,000; if second digit is '2', the end of 2nd year payment will be BDT 2,000; if any digit is '0' the corresponding end of year payment will be BDT 0. Interest rate is 7.5% (i) Draw cash flow diagram, (ii) Determine PW, FW and AW using equations
