Since time and intrest must be calculated in year so month convert into year.

amt=present worth + true discount
pw=amt-td
2562-122
pw=2440
TIME=4MONTHS/12=1/3
SI=PTR/100
PTR=SI*100
R=(SI*100)/PT
R=(122*100)/2440*1/3
R=15%
pw=amt-td
2562-122
pw=2440
TIME=4MONTHS/12=1/3
SI=PTR/100
PTR=SI*100
R=(SI*100)/PT
R=(122*100)/2440*1/3
R=15%

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%
