find the discounted value of 500 due in 82 days at 9%, 1000 at 55 days at 15% using both ordinary and simplest interest?

1 answer

Ordinary Interest
Ar = Ab - Ab*r*t.
Ar = 500 - 500*(0.09/360)*82 =
Amount received or Discounted value.

Ar = 1000 - 1000*(0.15/360)*55 =
Amount received or Discounted value.
