@Ankush.
Amount = present worth + true discount.
pw = amt - td.
2562 - 122.
pw = 2440.
TIME = 4 MONTHS / 12 =1/3.
SI = PTR / 100.
PTR = SI * 100.
R = (SI * 100) /PT.
R = (122 * 100) /2440 * 1/3.
You have finally get the answer for the rate of present value, below.
R = 15%.
Amount = present worth + true discount.
pw = amt - td.
2562 - 122.
pw = 2440.
TIME = 4 MONTHS / 12 =1/3.
SI = PTR / 100.
PTR = SI * 100.
R = (SI * 100) /PT.
R = (122 * 100) /2440 * 1/3.
You have finally get the answer for the rate of present value, below.
R = 15%.

In the question there must not mention that true discount amount is inclusive or exclusive on Rs. 2562/-.
How anyone could assumed to be that?
Answer should be 14% if it is exclusive or 15% if it is inclusive.

P.W = Amount - T.D.
So P.W = 2440.
T.D = (P.W)*R*T.
100 they ask rate percent.
So R = (100*T. D)/(P.W*T) %.
R = (100*122)/(2440*1/3).
= (100*122*3)/(2440*1).
Answer: 15%.
So P.W = 2440.
T.D = (P.W)*R*T.
100 they ask rate percent.
So R = (100*T. D)/(P.W*T) %.
R = (100*122)/(2440*1/3).
= (100*122*3)/(2440*1).
Answer: 15%.

2562 is money = B.D = 122.
2562-122 = 2440.
Then 4/12 = 1/3.
1/3 = 122 days.
1/12 = 366 days.
100*366/2440 = 15%.
2562-122 = 2440.
Then 4/12 = 1/3.
1/3 = 122 days.
1/12 = 366 days.
100*366/2440 = 15%.

2562 is sum of the money borrowed and true discount for 4 months.
So 2562 = The money borrowed+122.
The money borrowed = 2562-122 = 2440.
Then,
4 months (1/3 year) ===> 122.
12 months (1 year) ===> 366.
And,
Rs. 2440 ===> 366.
Rs. 100 ===> (100*366)/2440 = 15 %
So 2562 = The money borrowed+122.
The money borrowed = 2562-122 = 2440.
Then,
4 months (1/3 year) ===> 122.
12 months (1 year) ===> 366.
And,
Rs. 2440 ===> 366.
Rs. 100 ===> (100*366)/2440 = 15 %
