Course: Financial Mathematics There are 3 promissory notes. First one is due in 3 months and its final amount at maturity is $1,200. Second one is due in 2 months and its final value is $5,000 and last one was taken on February 15 for 180 days, for $2,500 and a rate of 5.6%. Question: How much is VALUE of 3 promissory notes as of today (March 25) if DISCOUNT RATE is 7.4% and DEFAULT RATE is increased by 1 percentage point?

NOTE: I have already seen exercise developed at other web portals. What is not clear to me is that DEFERRED INTEREST and DISCOUNT RATE of 7.4% both omitted in development, why?

THANKS (:D
