Friends we can say T.D. = Interest on P.W. Hence the formula seems the same.

What about this?
122= 4months => 1month = 30.5 => for a year 12*30.5= 366
2562-122= 2440
366/2440= 0.15 => 15%
122= 4months => 1month = 30.5 => for a year 12*30.5= 366
2562-122= 2440
366/2440= 0.15 => 15%

What does true discount mean? is it means the amount of interest for a certain time of a certain amount of money?

How come 15% I can't understand since 122 is the interest for 4 months then for each month it is 30.5,
Then it should be 12.5%,
Since 10% 24.4 and 2.5 % is 6.1 so the should be 12.5%.
I guess can you explain it please.

Rate percent is normally calculated for a year by doing 30.5/2440 we are not calculating for a year since 30.5 corresponds to a month only.
