What is the effective rate of a 30000, non-interest bearing, simple discount, 5%, 60 day note?

Hii !

30000 due at the end of 60 years
I'll assume that the number of days in year is 360
I=30,000×0.05×(60÷360)=250

Cash in hand at the beginning of 60 days is
30,000−250=29,750

The effective rate is
R=I÷pt
R=250÷(29,750×(60÷360))
R=0.0504×100
R=5.04%
