This is a good video - Thanks for explaining. I noticed this is the kind of question that was in one of the CFA mock exams. However, what I don't get it is why is this different from the curriculum itself; where PV is given and we have to multiply by PV. Also there was no division by the last rate which is what you did here by dividing it by 3.20%. I am just confused which calculation to use when a question like this is given.
