Following is explanation:
First, Face Value of Bill (F) is to be found out.
Given that,
Present Worth (PW) = Rs. 800.
True Discount (TD) = Rs. 36 which is simple interest on Present Worth (PW).
=> TD = PW*T*R/100.
=> 36 = 800*T*R/100.
=> 36*100/800 = T*R.
=> T*R = 4.5..........equation (1).
We know, PW = F/[1+(T*R/100)].
=> PW*[1+(T*R/100)] = F.
=> 800*[1+(4.5/100)] = F.
=> 800*[104.5/100] = F.
=> F = Rs. 836..........equation (2).
Banker's Discount is simple interest on Face Value of Bill (F).
=> BD = F*T*R/100.
Using Equation (1) & (2),
=> BD = 836*4.5*(1/100).
=> BD = Rs. 37.62.
Thanks
